SEMICONDUCTOR KIA431 Series TECHNICAL DATA BIPOLAR LINEAR INTEGRATED CIRCUIT PROGRAMMABLE PRECISION REFERENCES The KIA431 Series integrated circuits are three-terminal programmable shunt regulator diodes. These monolithic IC voltage reference operate as a low temperature coefficient zener which is programmable from Vref to 36 volts with two external resistors. These devices exhibit a wide operating current range of 1.0 to 100mA with a typical dynamic impedance of 0.22.The characteristics of these references make them excellent replacements for zener diodes in many applications such as digital voltmeters, power supplies, and op amp circuitry. The 2.5 volt reference makes it convenient to obtain a stable reference from 5.0 volt logic supplies, and since the KIA431 Series operates as a shunt regulator, it can be used as either a positive or negative voltage reference.

Elements mounting styles of electronic devices are gaining in further diversification over recent years, and needs for components are all the more expanding in varieties. Especially, surface mounting is steadily penetrating into industrial segments as a world-wide popular technical trend. Although exposure to high temperature is inevitable during soldering we recommend limiting the soldering temperature to low levels as shown in figure for the sake of retaining inherent excellent reliability. _ 1sec 10 + _3 C Peak : 260 + Temperature ( C) 250 C 230 C 180 C 150 C _ 30sec 90 + _ 5sec 35 + Preheating Zone Reflow Zone Time (sec) [Lead-Free Soldering Temperature Profile] 1. When employing solder reflow method 1) Soldering Condition Standard Condition : 250 (Temperature), 101sec. (Time) Peak Condition : 2603 2) Recommend temperature profile 3) Precautions on heating method When resin in kept exposed to high temperature for a long time, device reliability may be marred. Therefore, it is essential to complete soldering in the shortest time possible to prevent temperature of resin from rising. 2. When employing halogen lamps or infrared-ray heaters When halogen lamps or infrared-ray heaters are used, avoid direct irradiation onto resin surfaces; such devices cause extensive localized temperature rise. Please keep a reflow solder operating when Surface Mount Package s Soldering. 2013. 4. 16 Revision No : 18 8/8
