DESCRIPTION
The VS-30BQ015-M3 surface mount Schottky rectifier has
been designed for applications requiring low forward drop
and very small foot prints on PC boards. The proprietary
barrier technology allows for reliable operation up to 125 °C
junction temperature. Typical applications are in disk drives,
switching power supplies, converters, freewheeling diodes,
battery charging, and reverse battery protection.
