DESCRIPTION
The VS-40L15CW... 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.
