Description/ Features
Major Ratings and Characteristics
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, free-wheeling diodes, battery
