Description/Features
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 powersupplies, converters, reverse battery protec-
tion, and redundant power subsystems.
