(per leg, Typical)
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.
