Description/ Features
The MBRD320, MBRD330, MBRD340 surface mount
Schottky rectifier has been designed for applications requiring
low forward drop and small foot prints on PC board. Typical
applications are in disk drives, switching power supplies,
converters, free-wheeling diodes, battery charging, and
reverse battery protection.
