Overview
The Nexperia BC817K-16VL is an NPN general-purpose transistor housed in a small SOT23 (TO-236AB) surface-mount plastic package. It features a collector-emitter voltage of 45 V and a continuous collector current of 500 mA, with a peak pulse current capability of 1 A. The device offers three distinct DC current gain selections; the -16 variant provides a minimum hFE of 100 at IC = 100 mA. Total power dissipation reaches 350 mW at 25 °C ambient temperature. The component is qualified to the AEC-Q101 automotive standard.
Feature Summary
- Three selectable current gain ranges for precise circuit biasing
- Qualified for automotive applications under AEC-Q101 standards
- High power dissipation capability within a compact SMD footprint
Applications
- General-purpose switching circuits
- Signal amplification stages
- Automotive electronic modules
Procurement Notes
Verify the specific ordering suffix against official Nexperia documentation to confirm exact binning and marking codes. Ensure the procurement channel sources directly from authorized distributors or Nexperia sales offices to guarantee authenticity. Confirm that the delivered components match the specified AEC-Q101 qualification status required for your design.
Selection Notes
Select this component when a low-voltage NPN switch requires defined gain bands. The SOT23 package suits space-constrained PCB layouts. Verify thermal management requirements based on the specific PCB copper area and layer count, as power dissipation varies significantly between free-air and mounted conditions.
Part Context
This part belongs to the BC817K series, which includes complementary PNP devices like the BC807K-16. The series utilizes silicon technology optimized for high current handling in small packages. The 'K' designation typically indicates specific packaging and reel configurations compared to non-K variants.
Replacement Considerations
Direct functional substitutes within the same family include BC817K-25 and BC817K-40, which share identical pinouts and ratings but offer different DC current gain ranges.
