Description/Features
The 82CNQ030A center tap Schottky rectifier module has
been optimized for very low forward voltage drop, with
moderate leakage. The proprietary barrier technology allows
for reliable operation up to 150 °C junction temperature.
Typical applications are in switching power supplies, convert-
ers, free-wheeling diodes, and reverse battery protection.
