Major Ratings and Characteristics

Description/ Features

The 400DMQ high current, Schottky rectifier doubler module

series has been optimized for very low forward voltage drop,

with moderate leakage. The proprietary barrier technology

allows for reliable operation up to 150 °C junction temperature.

Typical applications are in switching power supplies, convert-

ers, free-wheeling diodes, welding, and reverse battery

protection.
