Description/Features
The 111CNQO45A center tap Schottky rectifier module has
been optimized forvery low forward voltage drop, with moder-
ate leakage. The proprietary barrier technology allows for
reliable operation up to 175 "C junction temperature. Typical
applications are in switching power supplies, converters, free-
wheeling diodes, and reverse battery protection.
