Procurement Notes

Verify the specific ordering suffix matches the required tape-and-reel quantity and packaging format. Confirm that the DFN1110D-3 footprint aligns with your PCB design guidelines. Ensure compliance with RoHS directives and check for any regional export control restrictions applicable to this semiconductor component before finalizing procurement orders.

Selection Notes

Select this component when space constraints require an ultra-thin surface-mount package. The BC817-40QBH-QZ provides higher current gain than lower-grade variants, making it suitable for precise amplification tasks. Consider its AEC-Q101 qualification if designing for automotive environments requiring high reliability and temperature resilience up to 175 °C junction temperature.

Part Context

This part belongs to the Nexperia BC817QBH-Q series, which includes complementary PNP transistors like the BC807-40QBH-QZ. The series utilizes the DFN1110D-3 package to minimize board area while maintaining robust electrical performance. It serves as a modern replacement for traditional SOT-23 packaged transistors in compact consumer and industrial electronics.

Replacement Considerations

Direct pin-compatible replacements within the same series include BC817-16QBH-QZ and BC817-25QBH-QZ, differing primarily in DC current gain ranges. For broader compatibility, verify electrical parameters against standard SOT-23 NPN transistors, ensuring voltage and current ratings meet or exceed original design requirements.
