SMC
The 30BQ015 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 125C junction
temperature. Typical applications are in disk drives, switching
power supplies, converters, free-wheeling diodes, battery
charging, and reverse battery protection.
