Description / Features
The 30BQ015 surface-mount Schottky rectifier has been de-
signed for applications requiring very low forward drop and
small foot prints on PC boards. Typical applications are in disk
drives, switching power supplies, converters, free-wheeling
diodes, battery charging and reverse battery protection.
• Small footprint, surface mountable
• Very low forward voltage drop
• High frequency operation
• Guard ring for enhanced ruggedness and long-term
reliability
