The 403CMQ 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, plating power supplies,

UPS systems, converters, free-wheeling diodes, welding, and

reverse battery protection.
