Procurement Notes

Verify the specific suffix codes against official Nexperia documentation to confirm exact electrical tolerances and packaging configurations. Ensure that the automotive qualification status aligns with project requirements. Cross-reference the part number with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component when an NPN transistor with AEC-Q101 automotive qualification is required in a small SOT323 package. It serves as a suitable alternative to standard commercial grade transistors in applications demanding higher reliability. Consider the 65 V voltage rating and 100 mA current limit during circuit design to ensure operation within safe limits.

Part Context

This component belongs to the BC846 series of NPN general-purpose transistors produced by Nexperia. The series offers various gain grades and package options. The QC-QZ designation indicates specific automotive qualification and packaging attributes distinct from standard commercial variants within the same family.

Replacement Considerations

Direct substitutes include other AEC-Q101 qualified NPN transistors in the SOT323 package with matching 65 V and 100 mA ratings. Verify pinout compatibility and thermal characteristics before substitution.
