Selection Notes
Select this component when a low-voltage, low-current NPN switch or amplifier is required in a compact SOT-23 footprint. Ensure the design accounts for the 250 mW power dissipation limit and the specified hFE range. Consider the AEC-Q101 qualification if the application demands automotive-grade reliability standards.
Part Context
This part belongs to the BC850 series of NPN transistors. It serves as the complement to the BC860B PNP transistor. The device is designed for surface-mount assembly on printed-circuit boards, offering a small physical profile suitable for space-constrained electronic designs requiring reliable switching performance.
Replacement Considerations
The BC860B is the designated PNP complement. Verify pinout compatibility and electrical limits before substituting with other NPN transistors in the same package family.
