Reliability data
Test Test methods/conditions Requirement
Varistor voltage The voltage between two terminals with
the specified measuring current applied
is called VV(1 mADC @ 0.2 ... 2 s).
To meet the specified value
Clamping voltage The maximum voltage between two
terminals with the specified standard
impulse current (8/20 µs) applied.
To meet the specified value
Endurance at upper
category temperature
1000 h at UCT
After having continuously applied the
maximum allowable AC voltage at UCT
±2°C for 1000 h, the specimen shall be
stored at room temperature and normal
humidity for 1 to 2 h.
Thereafter, the change of VVshall be
measured.
|∆V/V (1 mA)| ≤10%
Surge current derating,
8/20 µs
10 surge currents (8/20 µs), unipolar,
interval 30 s, amplitude corresponding
to derating curve for 10 impulses at
20 µs
|∆V/V (1 mA)| ≤10%
(measured in direction of
surge current)
No visible damage
Surge current derating,
2 ms
10 surge currents (2 ms), unipolar,
interval 120 s, amplitude corresponding
to derating curve for 10 impulses at
2 ms
|∆V/V (1 mA)| ≤10%
(measured in direction of
surge current)
No visible damage
Electric strength IEC 61051-1, test 4.9.2
Metal balls method, 2500 VRMS, 60 s
The varistor is placed in a container
holding 1.6 ±0.2 mm diameter metal
balls such that only the terminations of
the varistor are protruding.
The specified voltage shall be applied
between both terminals of the specimen
connected together and the electrode

(non-standard) are differently crimped for technical reasons; the individual crimp styles are denot-

Cautions and warnings
General
1. EPCOS metal oxide varistors are designed for specific applications and should not be used
for purposes not identified in our specifications, application notes and data books unless oth-
erwise agreed with EPCOS during the design-in-phase.
2. Ensure suitability of SIOVs through reliability testing during the design-in phase. SIOVs
should be evaluated taking into consideration worst-case conditions.
3. For applications of SIOVs in line-to-ground circuits based on various international and local
standards there are restrictions existing or additional safety measures required.
Storage
1. Store SIOVs only in original packaging. Do not open the package prior to processing.
2. Recommended storage conditions in original packaging:
Storage temperature: 25 °C ... +45 °C,
Relative humidity: <75% annual average,
<95% on maximum 30 days a year.
Dew precipitation: is to be avoided.
3. Avoid contamination of an SIOV's during storage, handling and processing.
4. Avoid storage of SIOVs in harmful environments that can affect the function during long-term
operation (examples given under operation precautions).
5. The SIOV type series should be soldered after shipment from EPCOS within the time speci-
fied:
SIOV-S, -Q, -LS, -B, -SNF 24 months
ETFV/ T series, -CU 12 months.
Handling
1. SIOVs must not be dropped.
2. Components must not be touched with bare hands. Gloves are recommended.
3. Avoid contamination of the surface of SIOV electrodes during handling, be careful of the
sharp edge of SIOV electrodes.
Soldering (where applicable)
1. Use rosin-type flux or non-activated flux.
2. Insufficient preheating may cause ceramic cracks.
3. Rapid cooling by dipping in solvent is not recommended.
4. Complete removal of flux is recommended.
5. Temperatures of all preheat stages and the solder bath must be strictly controlled especially
for T series (T14 and T20).
Leaded varistors B722*
StandarD series
Page 43 of 47Please read Cautions and warnings and
Important notes at the end of this document.
Mounting
1. Potting, sealing or adhesive compounds can produce chemical reactions in the SIOV ceramic
that will degrade the component’s electrical characteristics.
2. Overloading SIOVs may result in ruptured packages and expulsion of hot materials. For this
reason SIOVs should be physically shielded from adjacent components.
Operation
1. Use SIOVs only within the specified temperature operating range.
2. Use SIOVs only within the specified voltage and current ranges.
3. Environmental conditions must not harm SIOVs. Use SIOVs only in normal atmospheric con-
ditions. Avoid use in deoxidizing gases (chlorine gas, hydrogen sulfide gas, ammonia gas,
sulfuric acid gas etc), corrosive agents, humid or salty conditions.Contact with any liquids and
solvents should be prevented.
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. Detailed information can be found on the Internet
under www.epcos.com/orderingcodes

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 re-
quirements 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 incum-
bent on the customer to check and decide whether an EPCOS product with the properties de-
scribed 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 Ma-
terial Data Sheets on the Internet (www.epcos.com/material). Should you have any more de-
tailed 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 fore-
going for customer-specific products.
6. Unless otherwise agreed in individual contracts, all orders are subject to the current ver-
sion of the "General Terms of Delivery for Products and Services in the Electrical In-
dustry" published by the German Electrical and Electronics Industry Association
(ZVEI).
