BC856AQBZ

Overview

The BC856AQBZ is a PNP general-purpose transistor manufactured by Nexperia USA Inc. It operates with a maximum collector-emitter voltage of 65 V and a continuous collector current of 100 mA. The device utilizes an ultra-small DFN1110D-3 (SOT8015) leadless surface-mounted plastic package featuring side-wettable flanks. This component serves as the high-gain variant within the BC856 series, providing specific DC current gain characteristics suitable for precision switching and amplification tasks in space-constrained electronic designs.

Feature Summary

• Ultra-small footprint design utilizing a leadless DFN1110D-3 package with side-wettable flanks to facilitate Automatic Optical Inspection.
• High power dissipation capability integrated into a low profile package structure measuring 0.5 mm in height.
• Optimized for space-restricted applications requiring compact surface-mount solutions.

Applications

• General-purpose switching circuits
• Signal amplification stages
• Space-restricted electronic assemblies

Procurement Notes

Verify the complete part number including the suffix against official Nexperia documentation to ensure correct package and tape-and-reel specifications. Confirm that the required gain bin matches the 'A' designation. Cross-reference the SOT8015 package code with JEDEC MO-340BA standards to validate physical compatibility with existing PCB footprints before finalizing procurement orders.

Selection Notes

Select this component when a PNP transistor with a 65 V rating and 100 mA current capacity is required in a minimal footprint. The DFN1110D-3 package offers a smaller area compared to conventional leaded SMD packages. Ensure the application benefits from side-wettable flanks for improved solder joint inspection reliability via AOI systems.

Part Context

This device belongs to the Nexperia BC856 family of general-purpose PNP transistors. It is functionally paired with the BC846AQB NPN complement. The product line targets modern electronics demanding reduced board space while maintaining standard bipolar junction transistor performance metrics for signal processing and control logic.

Replacement Considerations

Direct substitutes include other BC856A variants in compatible packages such as SOT23 or SOT323 if footprint changes are permissible. Verify electrical parameters match the 65 V / 100 mA requirements. Check datasheets for equivalent gain bins and thermal characteristics before substituting.
