SCHOTTKY RECTIFIER
TO-244AB isolated
Major Ratings and Characteristics
Description/ Features
The 203CMQ high current Schottky rectifier module series
has been optimized for low reverse leakage at high tempera-
ture.
Characteristics
203CMQ... Units
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.
