Major Ratings and Characteristics
Characteristics
Description/ Features
The MBRA140TR surface mount Schottky rectifier has been
designed for applications requiring low forward drop and very
small foot prints on PC boards. Typical applications are in disk
drives, switching power supplies, converters, free-wheeling
diodes, battery charging, and reverse battery protection.
