Overview
The BC817-25-QVL is an NPN general-purpose transistor from the Nexperia BC817-Q series, housed in a SOT23 (TO-236AB) surface-mounted plastic package. It features a collector-emitter voltage of 45 V and a continuous collector current rating of 500 mA at 25 °C. The device supports a peak collector current of 1 A for single pulses up to 1 ms. DC current gain (hFE) is specified between 160 and 400 under standard test conditions. The component is qualified according to AEC-Q101 standards.
Feature Summary
- Qualified for automotive applications per AEC-Q101 standards
- Offers three distinct current gain selection groups
- Designed for high current switching and amplification tasks
Applications
- General-purpose switching circuits
- Amplification stages in electronic designs
- Automotive embedded systems
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct binning and packaging configuration. Confirm that the AEC-Q101 qualification status aligns with your project's automotive reliability requirements before finalizing procurement decisions.
Selection Notes
Select this variant when a specific DC current gain range of 160 to 400 is required for circuit stability. Ensure the operating environment stays within the specified thermal limits and that the 45 V collector-emitter voltage provides sufficient headroom for the intended application load.
Part Context
This component belongs to the BC817-Q series of NPN transistors designed for robust performance in demanding environments. The series includes variants with different gain characteristics, all sharing the same physical package and core electrical ratings. The Q-series designation indicates automotive-grade qualification.
Replacement Considerations
The BC807-25-Q serves as the PNP complement within the same series. Other BC817-Q variants with different gain bins may be considered if the specific hFE range is not critical, provided they meet the voltage and current requirements.
