Description/ Features
The 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.
