Description/Features
The 83CNQ...A center tap Schottky rectifier module series
has been optimized for low reverse leakage at high tempera-
ture. The proprietary barrier technology allows for reliable
operation up to 175 °C junction temperature. Typical applica-
tions are in switching power supplies, converters, free-
wheeling diodes, and reverse battery protection.
