DESCRIPTION
This center tap Schottky rectifier module has been
optimized for ultralow forward voltage drop specifically for
3.3 V output power supplies. The proprietary barrier
technology allows for reliable operation up to 150 °C
junction temperature. Typical applications are parallel
switching power supplies, converters, reverse battery
protection, and redundant power subsystems.
