SCHOTTKY RECTIFIER
2 Amp
20BQ030
Bulletin PD-20717 rev. G 0
7/04
1
The 20BQ030 surface-mount Schottky rectifier has been
designed for applications requiring 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 foot print, surface mountable
Very low forward voltage drop
High frequency operation
Guard ring for enhanced ruggedness and long term
reliability

Marking & Identification
Each device has 2 rows for identification. The first row designates the device as manufactured by International
Rectifier, indicated by the letters "IR", and the Part Number (indicates the current, the voltage rating and
Schottky Generation). The second row indicates the year, the week of manufacturing and the Site ID.
