Major Ratings and Characteristics

The 203CMQ high current Schottky rectifier module series

has been optimized for low reverse leakage at high tempera-

ture.

The proprietary barrier technology allows for reliable opera-

tion 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.
