BC856SF

Overview

The BC856SF is a dual PNP general-purpose transistor manufactured by Nexperia, housed in the SOT363 (SC-88) surface-mount plastic package. It integrates two independent PNP transistors within a single compact footprint to optimize printed circuit board space. The device supports a maximum continuous collector current of 100 mA and withstands a collector-emitter voltage of 65 V. Key electrical characteristics include a collector-base voltage rating of 80 V and an emitter-base voltage limit of 5 V. The component features a power dissipation capacity of 300 mW and a gain-bandwidth product of 100 MHz. It operates reliably across a temperature range from -65 °C to +150 °C.

Feature Summary

• Dual PNP configuration for efficient space-saving circuit design
• Low saturation voltage for improved switching efficiency
• High thermal stability with extended operating temperature range

Applications

• General-purpose switching circuits
• Signal amplification stages
• Logic level translation interfaces

Procurement Notes

Verify the specific suffix against official Nexperia documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with standard SMD reflow soldering profiles. Confirm RoHS compliance status through the manufacturer's latest environmental declaration before integration into regulated assemblies.

Selection Notes

Select this component when dual PNP functionality is required in minimal space. Compare performance against single-transistor alternatives if pin count constraints allow. Verify that the 100 mA current rating meets load requirements. Consider the SOT363 footprint dimensions during PCB layout planning.

Part Context

This part belongs to the BC856 series of general-purpose bipolar junction transistors. It serves as the dual-transistor variant within the family, complementing single-transistor options like the BC856W. The SOT363 package provides a smaller solution compared to traditional dual packages while maintaining similar electrical characteristics to the single-device counterparts.

Replacement Considerations

Direct pin-compatible substitutes include other dual PNP transistors in the SOT363 package. Verify electrical parameters match or exceed original specifications. Check for equivalent gain ranges and saturation voltages to ensure circuit performance consistency.
