Description/ Features
The 20BQ030 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
