Procurement Notes

Verify the specific suffix QX against official Nexperia documentation to confirm packaging details and availability status. Ensure compliance with RoHS directives and AEC-Q101 automotive standards matches project requirements before procurement. Cross-reference datasheet revisions to confirm parameter consistency.

Selection Notes

Select this component when space constraints require a dual NPN solution. Verify that the 500 mA current rating and 45 V voltage limits align with circuit demands. Consider the 600 mW power dissipation capability for thermal management planning. Confirm compatibility with automated optical inspection processes if required.

Part Context

This part belongs to the BC817 series of NPN general-purpose transistors. It serves as the dual-transistor variant of the single BC817 model. The series offers multiple gain selections and complements the BC807 PNP counterparts. Designed for surface-mount technology, it supports modern manufacturing techniques.

Replacement Considerations

Direct substitutes include other BC817DS variants from Nexperia or equivalent dual NPN transistors from manufacturers like Diodes Incorporated or onsemi. Verify pinout compatibility and electrical specifications match exactly before substitution.
