Description/ Features
The 50WQ10G surface mount Schottky rectifier has been
designed for applications requiring low forward drop and
small foot prints on PC board. Typical applications are in disk
drives, switching power supplies, converters, free-wheeling
diodes, battery charging, and reverse battery protection.
Popular D-PAK outline
Small foot print, surface moutable
Low forward voltage drop
High frequency operation
Guard ring for enhanced ruggedness and long term
reliability
