Procurement Notes

Verify the specific suffix 'QCZ' against official Nexperia documentation to confirm exact packaging configuration and reel specifications. Ensure the component matches the required SOT323 footprint and pinout for your design. Confirm AEC-Q101 compliance if automotive usage is intended. Cross-reference datasheet parameters with your system requirements before finalizing procurement decisions.

Selection Notes

Select this component when a compact NPN transistor with high voltage tolerance and automotive qualification is required. The SOT323 package suits designs with limited board space. Consider the 100 mA current limit and 200 mW power dissipation for thermal management. Verify that the 65 V breakdown voltage aligns with your circuit's operating conditions and signal levels.

Part Context

This part belongs to the BC846 series of general-purpose NPN transistors from Nexperia. It serves as the SOT323 packaged variant of the BC846B, offering a smaller footprint compared to the SOT-23 version. The series includes complementary PNP devices and other gain variants, providing flexibility for various general-purpose switching and amplification needs in consumer and automotive electronics.

Replacement Considerations

Direct substitutes include BC846BW-QX or BC846B-QR, provided the package type and electrical parameters match your design requirements. Verify pin compatibility and thermal characteristics when swapping between different package styles within the same series.
