Overview
The BC817-16QBZ is an NPN general-purpose transistor from the Nexperia BC817QB series, housed in a DFN1110D-3 (SOT8015) leadless SMD package. It features a collector-emitter voltage of 45 V and a continuous collector current of 500 mA. The device supports a peak collector current of 1 A and offers a DC current gain range of 100 to 250 at 100 mA. Total power dissipation reaches 350 mW at 25 °C on a standard FR4 PCB. The component is qualified under AEC-Q101 standards for automotive applications.
Feature Summary
- AEC-Q101 qualified for automotive reliability
- Leadless DFN package with side-wettable flanks for AOI inspection
- Ultra-thin 0.5 mm profile with small footprint
- High thermal performance capability
Applications
- General-purpose switching circuits
- Signal amplification stages
- Space-restricted electronic designs
Procurement Notes
Verify the specific ordering suffix matches the required reel or tape configuration. Confirm that the DFN1110D-3 package dimensions align with your PCB footprint requirements. Ensure design compliance with AEC-Q101 standards if intended for automotive use. Check the latest datasheet revision for any updates to thermal characteristics or marking codes before finalizing procurement.
Selection Notes
Select this component when a low-profile, leadless surface-mount solution is required for high-density layouts. The BC817-16QB variant provides a specific current gain band suitable for consistent amplification performance. Consider the side-wettable flank feature if Automatic Optical Inspection is critical for manufacturing quality control. Evaluate thermal resistance values against your expected operating temperature and PCB copper area constraints.
Part Context
This part belongs to the BC817QB series, which includes complementary PNP devices like the BC807-16QB. The series utilizes the SOT8015 package, distinguishing it from the traditional SOT23 packages found in earlier BC817 generations. The 'QB' designation indicates the specific leadless DFN form factor optimized for modern automated assembly processes.
Replacement Considerations
Direct pin-compatible replacements within the same package include other members of the BC817QB series, such as BC817-25QB or BC817-40QB, provided their current gain ranges meet circuit requirements. Standard SOT23 BC817 variants are not direct physical substitutes due to package differences.
