DESCRIPTION

The 115CNQ015A center tap 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.
