Overview
The Nexperia BC817-40/SNVL is an NPN general-purpose transistor housed in a SOT23 (TO-236AB) surface-mount package. It supports a maximum collector current of 500 mA and features a collector-emitter voltage rating of 45 V. The device offers a DC current gain range of 250 to 600 at 100 mA, with a peak collector current capability of 1 A for single pulses up to 1 ms. Thermal resistance from junction to ambient is specified at 500 K/W in free air.
Feature Summary
- High current handling capability suitable for demanding switching applications
- Three distinct current gain selections available within the series
Applications
- General-purpose switching circuits
- Amplification stages
Procurement Notes
Verify the specific ordering suffix against official Nexperia documentation to confirm package type and tape-and-reel specifications. Ensure the selected variant matches the required current gain binning for the intended circuit design. Cross-reference the part number with the latest product data sheet to confirm availability status and any recent manufacturing changes.
Selection Notes
Select this component when a compact NPN transistor with high current gain is required for signal amplification or load switching. The BC817-40 variant provides a guaranteed minimum hFE of 250, distinguishing it from lower-gain options in the same family. Consider thermal derating curves if operating near maximum power dissipation limits on standard PCB footprints.
Part Context
This component belongs to the BC817 series of NPN general-purpose transistors manufactured by Nexperia. The series includes variants with different current gain characteristics, such as BC817-16 and BC817-25. All members share the same SOT23 plastic surface-mounted package and fundamental electrical ratings, differing primarily in their DC current gain ranges.
