Overview
The Nexperia BC817K-25-QVL is an NPN general-purpose bipolar junction transistor (BJT) designed for surface-mount applications. It operates with a maximum collector-emitter voltage of 45V and supports a continuous collector current of 500mA. The device features a DC current gain (hFE) range of 160 to 400, ensuring consistent amplification performance. Packaged in the compact SOT-23 (TO-236AB) format, it offers a power dissipation capability of up to 350mW. This component meets AEC-Q101 automotive qualification standards and complies with RoHS directives.
Feature Summary
- Automotive-grade reliability certified under AEC-Q101 standards
- High current handling capability suitable for switching loads
- Compact SOT-23 package optimized for space-constrained designs
Applications
- General-purpose switching circuits
- Audio frequency amplification stages
- Automotive electronic control modules
Procurement Notes
Verify the specific suffix 'QVL' against official Nexperia documentation to confirm tape-and-reel packaging specifications and quantity per reel. Ensure the selected variant matches the required hFE binning and thermal characteristics for the target application environment.
Selection Notes
Select this component when high current gain and automotive durability are required in a small footprint. Compare against complementary PNP types like the BC807K series for push-pull configurations. Evaluate thermal management requirements based on the 350mW dissipation limit in the SOT-23 package.
Part Context
This part belongs to the BC817 family of NPN transistors, which provides standardized electrical characteristics across various manufacturers. The 'K' indicates the SOT-23 package, while '-25' specifies the 160-400 hFE gain range. The '-Q' denotes automotive qualification, making it suitable for harsh environments compared to standard commercial grades.
Replacement Considerations
Direct substitutes include other BC817-25 variants from different manufacturers such as Diodes Incorporated or STMicroelectronics, provided they match the SOT-23 package and AEC-Q101 qualification. Verify pinout compatibility and thermal resistance values before substitution.
