The 20CJQ100 surface mount Schottky rectifier series has
been designed for applications requiring very low forward drop
and very small foot prints. Typical applications are in portables,
switching power supplies, converters, automotive system, free-
wheeling diodes, battery charging, and reverse battery
protection.
Small footprint, surface mountable
Low profile
Very low forward voltage drop
High frequency operation
Guard ring for enhanced ruggedness and long term reliability
