PRODUCT SUMMARY
IF(AV) VR IRM 3.0 A 15 V 50 mA at 100 C
DESCRIPTION
The 30BQ015PBF 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.
