Description/ Features
The MBRD650CT, MBRD660CT surface mount, center tap,
Schottky rectifier series has been designed for applications
requiring low forward drop and small foot prints on PC board.
Typical applications are in disk drives, switching power sup-
plies, converters, free-wheeling diodes, battery charging, and
reverse battery protection.
