DESCRIPTION
The 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.
