BC856SH-QX

Overview

The BC856SH-QX is a PNP/PNP matched double transistor from Nexperia, designed for high-reliability applications. It operates with a maximum collector-emitter voltage of 65 V and a continuous collector current of 100 mA. The component is housed in a very small SOT363-3 (SC-88) Surface-Mounted Device plastic package. This device is qualified according to the AEC-Q101 standard, ensuring suitability for automotive environments. It supports high-temperature operations up to 175 °C, providing robust performance in demanding electronic circuits.

Feature Summary

• AEC-Q101 qualified for automotive reliability standards
• Matched current gain and base-emitter voltage characteristics
• Low collector capacitance and saturation voltage
• No mutual interference between internal transistors

Applications

• Current mirror circuits
• Differential amplifiers
• High-temperature applications up to 175 °C

Procurement Notes

Verify the specific suffix 'QX' against official Nexperia documentation to confirm tape-and-reel packaging details. Ensure the order matches the AEC-Q101 qualification requirements for your target automotive or industrial design. Cross-reference the SOT363-3 package dimensions during PCB layout to ensure proper footprint compatibility.

Selection Notes

Select this component when matched PNP transistor pairs are required in space-constrained designs. The SOT363-3 package offers a smaller footprint compared to conventional leaded options. Consider the 175 °C operating limit for thermal management. Verify that the 65 V rating meets the circuit's voltage requirements before implementation.

Part Context

This part belongs to the BC856SH series of general-purpose double transistors. It serves as the PNP complement to the BC846SH-QX NPN/NPN variant. Both devices share the same SOT363-3 package and automotive qualification profile, allowing for complementary pairing in balanced circuit architectures requiring minimal board space.

Replacement Considerations

The BCM856BSH is documented as a drop-in replacement for standard double transistors in similar packages. Verify pinout compatibility and electrical parameters before substitution. Ensure the alternative part meets the same AEC-Q101 qualification if automotive reliability is required.
