Major Ratings and Characteristics 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.
