Description/ Features
The 40L..CWPbF 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.
