DESCRIPTION

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

applications are in parallel switching power supplies.
