DESCRIPTION
The VS-STPS40L15CW... center tap Schottky rectifier
module has been optimized for ultra low forward voltage
drop specifically for the OR-ing of parallel power supplies.
The proprietary barrier technology allows for reliable
operation up to 125 °C junction temperature. Typical
applications are in parallel switching power supplies,
converters, reverse battery protection, and redundant
power subsystems.
