Overview
The BC817-16QCZ is an NPN general-purpose transistor from the Nexperia BC817QC series, housed in a DFN1412D-3 (SOT8009) leadless surface-mounted package. It features a collector-emitter voltage of 45 V and a continuous collector current of 500 mA. The device offers three current gain selections; the -16 variant provides a DC current gain range of 100 to 250 at IC = 100 mA. It supports peak collector currents up to 1 A and includes side-wettable flanks for improved solder joint inspection.
Feature Summary
- High power dissipation capability with low thermal resistance
- Suitable for Automatic Optical Inspection (AOI) due to side-wettable flanks
- AEC-Q101 qualified for automotive applications
- Ultra-small footprint with a package height of 0.5 mm
Applications
- General-purpose switching
- Amplification circuits
- Space-restricted electronic designs
Procurement Notes
Verify the specific ordering suffix matches the required tape-and-reel packaging configuration. Confirm that the DFN1412D-3 package dimensions align with the target PCB footprint. Ensure the selected current gain bin corresponds to the circuit design requirements. Check for RoHS compliance status if restricted substances are a concern.
Selection Notes
Select this component when a compact SMD solution with high current handling is required. The BC817-16QCZ is appropriate for designs needing a minimum hFE of 100. Consider the thermal derating curves for high-power applications. Verify compatibility with standard reflow soldering profiles for leadless packages.
Part Context
This part belongs to the BC817QC series, which includes complementary PNP devices like the BC807-16QC. The series is designed to replace traditional leaded transistors in modern surface-mount assemblies. The QC designation indicates qualification for automotive environments under AEC-Q101 standards.
Replacement Considerations
Direct pin-compatible replacements within the same series include BC817-25QC and BC817-40QC, which offer different current gain ranges. For legacy leaded equivalents, the BC817 in SOT-23 packages may serve as a functional substitute if board space permits.
