BC856S-QX

Overview

The BC856S-QX is a PNP/PNP matched double transistor manufactured by Nexperia. It is housed in the SOT363 (SC-88) Surface-Mounted Device plastic package. The device features a maximum collector current of 100 mA and a collector-emitter voltage rating of 65 V. Key electrical parameters include a collector-base voltage of 80 V, an emitter-base voltage of 5 V, and a power dissipation capability of 300 mW. The transition frequency is specified at 100 MHz, with an operating temperature range spanning from -65 °C to +150 °C.

Feature Summary

• PNP/PNP matched double transistor configuration
• Very small SOT363 (SC-88) surface-mount package
• Low collector capacitance for high-speed performance
• Low collector-emitter saturation voltage

Applications

• Current mirror circuits
• Differential amplifier applications
• General-purpose switching and amplification

Procurement Notes

Verify the specific suffix 'QX' against official Nexperia documentation to confirm automotive qualification status and tape-and-reel packaging details. Ensure the component meets AEC-Q101 standards if required for the target application. Cross-reference the manufacturer part number with distributor listings to confirm availability and authenticity before procurement.

Selection Notes

Select this component when space-constrained designs require matched PNP transistors in a compact SC-88 footprint. It serves as a suitable alternative to standard discrete transistors where board area is limited. Consider its low saturation voltage and matched characteristics for precision analog signal processing or efficient switching tasks in portable electronics.

Part Context

This component belongs to the BC856 series of general-purpose PNP transistors. While the standard BC856 utilizes an SOT23 package, the BC856S variant specifically employs the smaller SOT363 form factor. This series provides NPN complements such as the BC846 family, offering designers paired options for complementary circuit topologies.
