Description/Features
The 89CNQ...A 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 175°C junction temperature. Typical
applications are in switching power supplies, converters, free
wheeling diodes, and reverse battery protection.
