Description/ Features
Major Ratings and Characteristics
Characteristics
403DMQ... Units
The 403DMQ100 center tap 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.
