Characteristics
10BQ040
Units
The 10BQ040 surface-mount Schottky rectifier has been de-
signed for applications requiring low forward drop and very
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
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.
