Description/ Features
The 10WQ045FN 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
