Characteristics
82CNQ030 Units
The 82CNQ030 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 applica-
tions are in switching power supplies, converters, free-wheel-
ing diodes, and reverse battery protection.
