BC846BSH-QX

Overview

The BC846BSH-QX is an NPN/NPN general-purpose double transistor manufactured by Nexperia. It is housed in a SOT363-3 (SC-88) surface-mount plastic package with fully isolated internal transistors. Key electrical specifications include a collector-emitter voltage (VCEO) of 65 V, a collector current (IC) of 100 mA, and a collector-base voltage (VCBO) of 80 V. The device features closely matched current gain and low collector-emitter saturation voltage. It is qualified according to AEC-Q101 standards, supporting high-temperature applications up to 175 °C.

Feature Summary

• AEC-Q101 qualified for automotive reliability
• Low collector capacitance for high-speed performance
• Closely matched current gain characteristics
• Fully isolated dual transistors in compact package

Applications

• General-purpose switching circuits
• Differential amplifier configurations
• Current mirror applications
• High-temperature automotive electronics

Procurement Notes

Verify the specific suffix 'QX' against official Nexperia documentation to confirm tape-and-reel packaging details and exact binning. Ensure the component meets AEC-Q101 requirements for your target automotive application. Cross-reference datasheets for thermal resistance values under your specific PCB layout conditions.

Selection Notes

Select this component when space-constrained designs require two matched NPN transistors in a single SC-88 footprint. It serves as a drop-in replacement for standard discrete double transistors where gain matching and isolation are critical. Consider its 175 °C operating limit for environments exceeding standard industrial temperature ranges.

Part Context

This part belongs to the BC846 series of general-purpose NPN transistors from Nexperia. While the standard BC846B is a single transistor in SOT-23, the BC846BSH variant integrates two NPN transistors in the smaller SOT363 package. The '-Q' suffix indicates automotive qualification, and '-X' typically denotes reel packaging.

Replacement Considerations

Standard BC846BS may be considered if automotive qualification is not required. For single-transistor needs, BC846B in SOT-23 offers higher power dissipation. Verify pinout compatibility before substituting with other SC-88 dual transistors.
