125 C TJ operation (VR < 5 V) Center tap module Pb-free Available Optimized for OR-ing applications RoHS* Ultra low forward voltage drop COMPLIANT High frequency operation Guard ring for enhanced ruggedness and long term reliability High purity, high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance Lead (Pb)-free ("PbF" suffix) Designed and qualified for industrial level

PRODUCT SUMMARY
IF(AV) VR IRM 20 A 15 V 600 mA at 100 C

DESCRIPTION
The Schottky rectifier module has been optimized for ultra low forward voltage drop specifically for the OR-ing of parallel power supplies. The proprietary barrier technology allows for reliable operation up to 125 C junction temperature. Typical applications are in parallel switching power supplies, converters, reverse battery protection, and redundant power subsystems.
