Characteristics
10BQ015 Units
The 10BQ015 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.
