Description/ Features
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 tempera-
ture. Typical applications are in parallel switching power
supplies, converters, reverse battery protection, and redun-
dant power subsystems.
