Description / Features
The 20CJQ100 surface-mount Schottky rectifier 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 systems,
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
• Common Cathode
