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.
