Description/Features
The 111CNQ045A center tap Schottky rectifier module has
been optimized for very 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.
