BC856BW-QF

Overview

The BC856BW-QF is a PNP general-purpose transistor manufactured by Nexperia USA Inc. It features a maximum collector-emitter voltage of 65 V and a continuous collector current of 100 mA. The device utilizes an SOT-323 (SC-70) surface-mount package with a maximum power dissipation of 200 mW. Key electrical characteristics include a DC current gain (hFE) of at least 220 at 2 mA and 5 V, a transition frequency of 100 MHz, and a collector cutoff current of 15 nA. The saturation voltage is specified at 600 mV under specific test conditions.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q101 standards for enhanced reliability in vehicle environments
• General-purpose switching and amplification capabilities within a compact surface-mount footprint
• Low saturation voltage design to minimize power loss during conduction

Applications

• General-purpose switching circuits
• Signal amplification stages
• Automotive electronic control units

Procurement Notes

Verify the specific suffix 'QF' against official Nexperia documentation to confirm exact binning or tape-and-reel specifications. Ensure the component meets AEC-Q101 requirements if intended for automotive use. Cross-reference the datasheet revision date to validate parameter consistency before finalizing procurement orders.

Selection Notes

Select this component when a PNP transistor with automotive reliability is required in space-constrained designs. The SOT-323 package offers a smaller footprint compared to standard SOT-23 variants while maintaining similar electrical performance. Consider the hFE range and thermal dissipation limits relative to the specific circuit load requirements.

Part Context

This part belongs to the BC856 family of PNP transistors produced by Nexperia. The 'Q' suffix typically denotes automotive-grade qualification, distinguishing it from standard commercial versions like the BC856BW. It serves as the PNP complement to the BC846 series NPN transistors, providing matched performance characteristics for complementary push-pull configurations.

Replacement Considerations

Direct substitutes include the BC856BW and BC856B. Verify that alternative parts meet the same AEC-Q101 automotive qualification standards if the application requires them. Check pinout compatibility and package dimensions to ensure mechanical interchangeability without PCB redesign.
