Please read Cautions and warnings and Important notes at the end of this document. Page 63 of 79 Multilayer varistors (MLVs) Standard series Soldering directions 1 Terminations 1.1 Nickel barrier termination The nickel barrier layer of the silver/nickel/tin termination prevents leaching of the silver base metallization layer. This allows great flexibility in the selection of soldering parameters. The tin prevents the nickel layer from oxidizing and thus ensures better wetting by the solder. The nickel barrier termination is suitable for all commonly-used soldering methods, including lead-free soldering. Multilayer CTVS: Structure of nickel barrier termination 1.2 Silver-platinum termination Silver-platinum terminations are mainly used for the large EIA case sizes 1812 and 2220. The silver-platinum termination is approved for reflow soldering, SnPb soldering and lead-free soldering with a silver containing solder paste. In case of SnPb soldering, a solder paste Sn62Pb36Ag2 is recommended. For lead-free reflow soldering, a solder paste SAC, e.g. Sn95.5Ag3.8Cu0.7, is recommended.

The nickel barrier layer is 100% matte tin-plated. 3.3 Silver-platinum terminated MLVs The silver-platinum termination is approved for reflow soldering, SnPb soldering and lead-free with a silver containing solder paste. In case of SnPb soldering, a solder paste Sn62Pb36Ag2 is recommended. For lead-free reflow soldering, a solder paste SAC, e.g. Sn95.5Ag3.8Cu0.7, is recommended. 3.4 Tinned iron wire All EPCOS SHCV types with tinned termination are approved for lead-free and SnPb soldering. 4 Solder joint profiles / solder quantity 4.1 Nickel barrier termination If the meniscus height is too low, that means the solder quantity is too low, the solder joint may break, i.e. the component becomes detached from the joint. This problem is sometimes interpreted as leaching of the external terminations. If the solder meniscus is too high, i.e. the solder quantity is too large, the vise effect may occur. As the solder cools down, the solder contracts in the direction of the component. If there is too much solder on the component, it has no leeway to evade the stress and may break, as in a vise. The figures below show good and poor solder joints for dual-wave and infrared soldering. Please read Cautions and warnings and Important notes at the end of this document.

Leaching of the outer electrode should not exceed 25% of the chip end area (full length of the edge A-B-C-D) and 25% of the length A-B, shown below as mounted on substrate. As a single chip 6 As mounted on substrate Notes for proper soldering 6.1 Preheating and cooling According to JEDEC J-STD-020D. Please refer to section 2 of this chapter. 6.2 Repair/ rework Manual soldering with a soldering iron must be avoided, hot-air methods are recommended for rework purposes. 6.3 Cleaning All environmentally compatible agents are suitable for cleaning. Select the appropriate cleaning solution according to the type of flux used. The temperature difference between the components and cleaning liquid must not be greater than 100 C. Ultrasonic cleaning should be carried out with the utmost caution. Too high ultrasonic power can impair the adhesive strength of the metallized surfaces. 6.4 Solder paste printing (reflow soldering) An excessive application of solder paste results in too high a solder fillet, thus making the chip more susceptible to mechanical and thermal stress. Too little solder paste reduces the adhesive strength on the outer electrodes and thus weakens the bonding to the PCB. The solder should be applied smoothly to the end surface. Please read Cautions and warnings and Important notes at the end of this document. Page 70 of 79 Multilayer varistors (MLVs) Standard series 6.5 Selection of flux Used flux should have less than or equal to 0.1 wt % of halogenated content, since flux residue after soldering could lead to corrosion of the termination and/or increased leakage current on the surface of the component. Strong acidic flux must not be used. The amount of flux applied should be carefully controlled, since an excess may generate flux gas, which in turn is detrimental to solderability. 6.6 Storage of CTVSs Solderability is guaranteed for one year from date of delivery for multilayer varistors, CeraDiodes and ESD/EMI filters (half a year for chips with AgPt terminations) and two years for SHCV components, provided that components are stored in their original packages. Storage temperature: 25 C to +45 C Relative humidity: 75% annual average, 95% on 30 days a year The solderability of the external electrodes may deteriorate if SMDs and leaded components are stored where they are exposed to high humidity, dust or harmful gas (hydrogen chloride, sulfurous acid gas or hydrogen sulfide). Do not store SMDs and leaded components where they are exposed to heat or direct sunlight. Otherwise the packing material may be deformed or SMDs/ leaded components may stick together, causing problems during mounting. After opening the factory seals, such as polyvinyl-sealed packages, it is recommended to use the SMDs or leaded components as soon as possible. Solder CTVS components after shipment from EPCOS within the time specified: CTVS with Ni barrier termination: CTVS with AgPt termination: SHCV (leaded components): 6.7 12 months 6 months 24 months Placement of components on circuit board Especially in the case of dual-wave soldering, it is of advantage to place the components on the board before soldering in that way that their two terminals do not enter the solder bath at different times. Ideally, both terminals should be wetted simultaneously. Please read Cautions and warnings and Important notes at the end of this document. Page 71 of 79 Multilayer varistors (MLVs) Standard series 6.8 Soldering cautions An excessively long soldering time or high soldering temperature results in leaching of the outer electrodes, causing poor adhesion and a change of electrical properties of the varistor due to the loss of contact between electrodes and termination. Wave soldering must not be applied for MLVs designated for reflow soldering only (see table "Overview", section 3.1). Keep the recommended down-cooling rate. 6.9 Standards CECC 00802 IEC 60068-2-58 IEC 60068-2-20 JEDEC J-STD-020D Please read Cautions and warnings and Important notes at the end of this document.

Page 74 of 79 Multilayer varistors (MLVs) Standard series Cautions and warnings General Some parts of this publication contain statements about the suitability of our ceramic transient voltage suppressor (CTVS) components (multilayer varistors (MLVs)), CeraDiodes, ESD/EMI filters, leaded transient voltage/ RFI suppressors (SHCV types)) for certain areas of application, including recommendations about incorporation/design-in of these products into customer applications. The statements are based on our knowledge of typical requirements often made of our CTVS devices in the particular areas. We nevertheless expressly point out that such statements cannot be regarded as binding statements about the suitability of our CTVS components for a particular customer application. As a rule, EPCOS is either unfamiliar with individual customer applications or less familiar with them than the customers themselves. For these reasons, it is always incumbent on the customer to check and decide whether the CTVS devices with the properties described in the product specification are suitable for use in a particular customer application. Do not use EPCOS CTVS components for purposes not identified in our specifications, application notes and data books. Ensure the suitability of a CTVS in particular by testing it for reliability during design-in. Always evaluate a CTVS component under worst-case conditions. Pay special attention to the reliability of CTVS devices intended for use in safety-critical applications (e.g. medical equipment, automotive, spacecraft, nuclear power plant). Design notes Always connect a CTVS in parallel with the electronic circuit to be protected. Consider maximum rated power dissipation if a CTVS has insufficient time to cool down between a number of pulses occurring within a specified isolated time period. Ensure that electrical characteristics do not degrade. Consider derating at higher operating temperatures. Choose the highest voltage class compatible with derating at higher temperatures. Surge currents beyond specified values will puncture a CTVS. In extreme cases a CTVS will burst. If steep surge current edges are to be expected, make sure your design is as low-inductance as possible. In some cases the malfunctioning of passive electronic components or failure before the end of their service life cannot be completely ruled out in the current state of the art, even if they are operated as specified. In applications requiring a very high level of operational safety and especially when the malfunction or failure of a passive electronic component could endanger human life or health (e.g. in accident prevention, life-saving systems, or automotive battery line applications such as clamp 30), ensure by suitable design of the application or other measures (e.g. installation of protective circuitry or redundancy) that no injury or damage is sustained by third parties in the event of such a malfunction or failure. Only use CTVS components from the automotive series in safety-relevant applications. Please read Cautions and warnings and Important notes at the end of this document. Page 75 of 79 Multilayer varistors (MLVs) Standard series Specified values only apply to CTVS components that have not been subject to prior electrical, mechanical or thermal damage. The use of CTVS devices in line-to-ground applications is therefore not advisable, and it is only allowed together with safety countermeasures like thermal fuses. Storage Only store CTVS in their original packaging. Do not open the package prior to processing. Storage conditions in original packaging: temperature 25 to +45C, relative humidity 75% annual average, maximum 95%, dew precipitation is inadmissible. Do not store CTVS devices where they are exposed to heat or direct sunlight. Otherwise the packaging material may be deformed or CTVS may stick together, causing problems during mounting. Avoid contamination of the CTVS surface during storage, handling and processing. Avoid storing CTVS devices in harmful environments where they are exposed to corrosive gases for example (SOx, Cl). Use CTVS as soon as possible after opening factory seals such as polyvinyl-sealed packages. Solder CTVS components after shipment from EPCOS within the time specified: CTVS with Ni barrier termination, 12 months CTVS with AgPt termination, 6 months SHCV, 24 months Handling Do not drop CTVS components and allow them to be chipped. Do not touch CTVS with your bare hands - gloves are recommended. Avoid contamination of the CTVS surface during handling. Washing processes may damage the product due to the possible static or cyclic mechanical loads (e.g. ultrasonic cleaning). They may cause cracks to develop on the product and its parts, which might lead to reduced reliability or lifetime. Mounting When CTVS devices are encapsulated with sealing material or overmolded with plastic material, electrical characteristics might be degraded and the life time reduced. Make sure an electrode is not scratched before, during or after the mounting process. Make sure contacts and housings used for assembly with CTVS components are clean before mounting. The surface temperature of an operating CTVS can be higher. Ensure that adjacent components are placed at a sufficient distance from a CTVS to allow proper cooling. Avoid contamination of the CTVS surface during processing. Please read Cautions and warnings and Important notes at the end of this document. Page 76 of 79 Multilayer varistors (MLVs) Standard series Soldering Complete removal of flux is recommended to avoid surface contamination that can result in an instable and/or high leakage current. Use resin-type or non-activated flux. Bear in mind that insufficient preheating may cause ceramic cracks. Rapid cooling by dipping in solvent is not recommended, otherwise a component may crack. Operation Use CTVS only within the specified operating temperature range. Use CTVS only within specified voltage and current ranges. Environmental conditions must not harm a CTVS. Only use them in normal atmospheric conditions. Reducing the atmosphere (e.g. hydrogen or nitrogen atmosphere) is prohibited. Prevent a CTVS from contacting liquids and solvents. Make sure that no water enters a CTVS (e.g. through plug terminals). Avoid dewing and condensation. EPCOS CTVS components are mainly designed for encased applications. Under all circumstances avoid exposure to: direct sunlight rain or condensation steam, saline spray corrosive gases atmosphere with reduced oxygen content EPCOS CTVS devices are not suitable for switching applications or voltage stabilization where static power dissipation is required. This listing does not claim to be complete, but merely reflects the experience of EPCOS AG. Display of ordering codes for EPCOS products The ordering code for one and the same EPCOS product can be represented differently in data sheets, data books, other publications, on the EPCOS website, or in order-related documents such as shipping notes, order confirmations and product labels. The varying representations of the ordering codes are due to different processes employed and do not affect the specifications of the respective products.

Page 77 of 79 Important notes The following applies to all products named in this publication: 1. Some parts of this publication contain statements about the suitability of our products for certain areas of application. These statements are based on our knowledge of typical requirements that are often placed on our products in the areas of application concerned. We nevertheless expressly point out that such statements cannot be regarded as binding statements about the suitability of our products for a particular customer application. As a rule, EPCOS is either unfamiliar with individual customer applications or less familiar with them than the customers themselves. For these reasons, it is always ultimately incumbent on the customer to check and decide whether an EPCOS product with the properties described in the product specification is suitable for use in a particular customer application. 2. We also point out that in individual cases, a malfunction of electronic components or failure before the end of their usual service life cannot be completely ruled out in the current state of the art, even if they are operated as specified. In customer applications requiring a very high level of operational safety and especially in customer applications in which the malfunction or failure of an electronic component could endanger human life or health (e.g. in accident prevention or lifesaving systems), it must therefore be ensured by means of suitable design of the customer application or other action taken by the customer (e.g. installation of protective circuitry or redundancy) that no injury or damage is sustained by third parties in the event of malfunction or failure of an electronic component. 3. The warnings, cautions and product-specific notes must be observed. 4. In order to satisfy certain technical requirements, some of the products described in this publication may contain substances subject to restrictions in certain jurisdictions (e.g. because they are classed as hazardous). Useful information on this will be found in our Material Data Sheets on the Internet (www.epcos.com/material). Should you have any more detailed questions, please contact our sales offices. 5. We constantly strive to improve our products. Consequently, the products described in this publication may change from time to time. The same is true of the corresponding product specifications. Please check therefore to what extent product descriptions and specifications contained in this publication are still applicable before or when you place an order. We also reserve the right to discontinue production and delivery of products. Consequently, we cannot guarantee that all products named in this publication will always be available. The aforementioned does not apply in the case of individual agreements deviating from the foregoing for customer-specific products. 6.
