The BC856BW-QX 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 features a transition frequency of 100 MHz and a power dissipation rating of 200 mW. It utilizes the SOT-323 (SC-70) surface-mount package. The component meets AEC-Q101 automotive qualification standards, ensuring reliability for demanding environments. It supports an operating temperature range from -65°C to +150°C junction temperature.
Verify the specific suffix QX against official Nexperia documentation to confirm AEC-Q101 qualification status. Ensure the ordering part number matches the exact package variant required for your PCB layout. Cross-reference the manufacturer's latest datasheet for any recent packaging or assembly changes. Confirm RoHS compliance details directly with the supplier. Validate that the component meets all environmental specifications for your intended application before finalizing procurement.
Select this component when automotive qualification is mandatory for PNP switching applications. The SOT-323 package suits designs requiring minimal board space. Consider the 65 V breakdown voltage for low-voltage signal processing tasks. Evaluate the 100 mA current limit against load requirements. Verify thermal management needs given the 200 mW power dissipation constraint in compact enclosures.
This part belongs to the BC856 family of PNP transistors designed for general-purpose use. It serves as the complement to the BC846 series NPN devices. The BC856BW variant specifically offers high DC current gain selection. The QX suffix indicates automotive grade qualification within the broader BC856 product line.
BC856BW,115 is a confirmed equivalent part number within the same family.
