The 89CNQ 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.
