Description/Features

The 401CMQ center tap, high current, Schottky rectifier module

series has been optimized for low reverse leakage at high

temperature. The proprietary barrier technology allows for

reliable operation up to 175° C junction temperature. Typical

applications are in high current switching power supplies,

converters, free-wheeling diodes, welding and reverse battery

protection.
