DESCRIPTION
The VS-MBRS140-M3 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, freewheeling diodes, battery charging, and
reverse battery protection.
