The BC856AQCZ 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 is housed in an ultra-small DFN1412D-3 (SOT8009) leadless surface-mounted package featuring side-wettable flanks for enhanced solder joint inspection. This component serves as a compact alternative to conventional leaded SMD packages, offering low profile characteristics suitable for space-constrained electronic designs.
Verify the specific suffix 'QCZ' against official Nexperia documentation to confirm exact tape-and-reel specifications and manufacturing origin. Ensure compatibility with automated pick-and-place equipment due to the leadless DFN form factor. Confirm RoHS compliance status through the latest datasheet revision before final procurement approval.
Select this component when board real estate is limited and high-density mounting is required. The DFN1412D-3 package provides a smaller footprint compared to standard SOT23 or SC-70 alternatives. Consider the AOI-friendly side-wettable flanks if production lines rely heavily on automated visual inspection for solder quality assurance.
This part belongs to the Nexperia BC856 series of PNP general-purpose transistors. While the standard BC856 utilizes the SOT23 package, the AQCZ variant specifically employs the DFN1412D-3 (SOT8009) package. It pairs electrically with the BC846A NPN complement within the same product family.
Direct physical replacement requires matching the DFN1412D-3 (SOT8009) package dimensions. Standard BC856A devices in SOT23 packages are not pin-compatible without PCB layout modifications.
