Description/Features
The 30BQ100 surface-mount Schottky rectifier has been designed for applications requiring low forward drop and small foot
prints on PC boards. Typical applications are in disk drives,
switching power supplies, converters, free-wheeling diodes,
battery charging, and reverse battery protection.
Small foot print, surface mountable
Very low forward voltage drop
High frequency operation
Guard ring for enhanced ruggedness and long term
reliability
