DESCRIPTION
The center tap Schottky rectifier module has been optimized
for ultralow 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.
