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