TECHNICAL DATA
PROGRAMMABLE PRECISION REFERENCES
The KIA431AA/BA/CA Series integrated circuits are three-terminal
programmable shunt regulator diodes.

L
B
L
These monolithic IC voltage reference operate as a low temperature
coefficient zener which is programmable from Vref to 36 volts with two
external resistors. It features a low mnimum cathode current for regulation.
The typical value of 50uA make the parts ideal for low power application.
These devices exhibit a wide operating current range of 0.1mA to 100mA
with a typical dynamic impedance of 0.22Ω .
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 KIA431AA/BA/CA Series
operates as a shunt regulator, it can be used as either a positive or negative
voltage reference.

PRECAUTION FOR USE
Lead-Free Soldering Condition.
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.

1. When employing solder reflow method
1) Soldering Condition
ⓐ Standard Condition : 250℃ (Temperature), 10±1sec. (Time)
ⓑ Peak Condition : 260±3℃
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.
