Procurement Notes
Verify the specific suffix 'QX' against the official Nexperia ordering information table to confirm packaging details such as reel size or tape width. Ensure the component matches the DFN2020-3 package outline dimensions and pin assignment defined in the datasheet. Confirm AEC-Q101 qualification status if automotive compliance is required for the final assembly.
Selection Notes
Select this component for designs requiring low forward voltage drop and high reliability in compact spaces. The exposed cathode pad facilitates efficient heat dissipation, making it suitable for applications with moderate power dissipation requirements. Verify that the PCB footprint accommodates the leadless SOT1061 package dimensions and solder mask specifications provided in the datasheet.
