Description/Features
The 50WQ..F surface mount Schottky rectifier has been de-
signed 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
