Procurement Notes

Verify the specific suffix 'QF' against official Nexperia documentation to confirm package type and tape-and-reel specifications. Ensure the selected variant meets the required gain banding and automotive quality standards for your application design.

Selection Notes

Select this component when automotive qualification is mandatory alongside small form factor requirements. Compare the 200 mW power dissipation limit against thermal constraints. Verify that the 100 mA current rating aligns with load requirements compared to higher-current alternatives.

Part Context

This part belongs to the BC846 series of NPN transistors, which includes variants like BC846W and BC846BW. The 'A' designation typically indicates a specific DC current gain range, while the 'Q' suffix denotes automotive grade compliance. It serves as the NPN complement to the BC856AW series.

Replacement Considerations

Potential substitutes include BC846W,115 or BC846BW-QX if gain ranges match. Verify pinout compatibility and thermal performance before substitution.
