Major Ratings and Characteristics
Description/ Features
The 183NQ high current 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 switching power supplies, converters, free-wheeling
diodes, and reverse battery protection.
