403CNQ...(R) SERIES
SCHOTTKY RECTIFIER
400 Amp
TO-244AB
Major Ratings and Characteristics
Description/Features
The 403CNQ center tap Schottky rectifier module series has
been optimized for low reverse leakage at high temperature.
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.
