SCHOTTKY RECTIFIER
80 Amp
Major Ratings and Characteristics
Description/Features
The 81CNQ center tap Schottky rectifier module series has
been optimized for low reverse leakage at high temperature.
Theproprietarybarriertechnologyallowsforreliableoperation
up to 175 °C junction temperature. Typical applications are in
switching power supplies, converters, free-wheeling diodes,
and reverse battery protection.
