The 30CPQ...PbF center tap Schottky rectifier 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.
