Major Ratings and Characteristics 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 temperature.

Typical applications are in parallel switching power supplies,

converters, reverse battery protection, and redundant power

subsystems.
