Characteristics
88CNQ...A Units
The 88CNQ060A 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 150C junction temperature. Typical
applications are in switching power supplies, converters, free
wheeling diodes, and reverse battery protection.
