Overview
The BC817-25/SNVL is an NPN general-purpose transistor from the Nexperia BC817 series, housed in a small SOT23 (TO-236AB) Surface-Mounted Device plastic package. It features a collector-emitter voltage of 45 V and a continuous collector current of 500 mA. The device offers a DC current gain range of 160 to 400 at VCE = 1 V and IC = 100 mA. Key electrical limits include a collector-base voltage of 50 V, an emitter-base voltage of 5 V, and a total power dissipation of 250 mW at Tamb ≤ 25 °C. The transition frequency is 100 MHz.
Feature Summary
- High current capability with a maximum collector current of 500 mA
- Three distinct current gain selections available within the series
- Small surface-mount footprint suitable for space-constrained designs
Applications
- General-purpose switching circuits
- Amplification applications
Procurement Notes
Verify the specific ordering suffix against official Nexperia documentation to confirm exact packaging and marking codes. Confirm that the component meets all required environmental and reliability standards for the intended application before finalizing procurement decisions.
Selection Notes
Select this variant when a specific DC current gain range between 160 and 400 is required. Ensure the operating conditions remain within the specified absolute maximum ratings to prevent permanent damage. Consider thermal resistance values when designing heat dissipation strategies for the SOT23 package.
Part Context
This component belongs to the BC817 series of NPN general-purpose transistors. The series includes variants with different current gain ranges, such as BC817-16 and BC817-40. All variants share the same SOT23 package and fundamental voltage and current ratings, differing primarily in their hFE specifications.
Replacement Considerations
Direct substitutes within the same family include BC817-16 and BC817-40, provided the specific current gain requirements align with those variants' characteristics. Verify pinout compatibility and package dimensions when considering alternative manufacturers.
FAQ
What is the marking code for the BC817-25?
The marking code for the BC817-25 is 6B, followed by a placeholder for the manufacturing site code.
What is the peak collector current rating?
The peak collector current (ICM) is rated at 1 A for single pulses with a duration of tp ≤ 1 ms at Tamb = 25 °C.
Is this product automotive qualified?
No, unless explicitly stated otherwise in specific data sheets, products in this series are not automotive qualified. Automotive alternatives are available separately.
