BC856BQB-QZ

Overview

The BC856BQB-QZ is a PNP general-purpose bipolar junction transistor (BJT) manufactured by Nexperia. 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-mount package featuring side-wettable flanks, which facilitates Automatic Optical Inspection (AOI). It offers high power dissipation capability and low package height. The component is qualified under the AEC-Q101 automotive standard, ensuring reliability for demanding environments.

Feature Summary

• Ultra-small leadless SMD plastic package with side-wettable flanks for enhanced solder joint inspection
• Qualified according to AEC-Q101 automotive reliability standards
• High power dissipation capability within a compact footprint

Applications

• General-purpose switching circuits
• Amplification applications
• Space-restricted electronic designs

Procurement Notes

Verify the specific suffix QZ against official Nexperia documentation to confirm package type and qualification status. Ensure the ordering part number matches the required AEC-Q101 automotive grade specifications. Cross-reference the manufacturer's datasheet for the BC856BQB series to validate pinout compatibility and thermal characteristics before integration into production designs.

Selection Notes

Select this component when space constraints require an ultra-small footprint compared to conventional leaded packages. The side-wettable flanks make it suitable for designs requiring reliable AOI verification of solder joints. Consider its AEC-Q101 qualification for automotive or high-reliability industrial applications where robust performance under varying thermal conditions is essential.

Part Context

This component belongs to the BC856 family of PNP general-purpose transistors from Nexperia. While the standard BC856 uses the SOT23 package, the BQB variant specifically employs the DFN1110D-3 (SOT8015) package. This family provides complementary NPN devices, such as the BC846AQB, maintaining consistent electrical characteristics across different form factors for design flexibility.

Replacement Considerations

Direct pin-to-pin replacements include other BC856B variants in the SOT8015 package, such as the BC856BQB without the automotive suffix if qualification is not required. Verify that alternative components maintain the same 65V rating, 100mA current capacity, and compatible thermal resistance values.
