Description/Features
The 322CNQ030 isolated 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 150° C junction temperature. Typical
applications are in switching power supplies, converters, free-
wheeling diodes, and reverse battery protection.
