DESCRIPTION
IF(AV)
The VS-STPS40L45CW... 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 switching power supplies.
