Overview
The BC817-16,235 is an NPN general-purpose transistor manufactured by Nexperia USA Inc. It operates with a collector-emitter voltage of 45 V and supports a continuous collector current of 500 mA. The device features a DC current gain (hFE) range of 100 to 250 at IC = 100 mA and VCE = 1 V. It utilizes a SOT23 (TO-236AB) surface-mount package with three leads. Key electrical limits include a collector-base breakdown voltage of 50 V and a total power dissipation of 250 mW at 25 °C ambient temperature.
Feature Summary
- High current capability for switching applications
- Three distinct current gain selections available within the series
Applications
- General-purpose switching
- Amplification circuits
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details such as reel size or tape configuration. Confirm that the component version matches the required automotive or non-automotive qualification status, as product specifications may vary based on the final two digits of the part number.
Selection Notes
Select this component when a moderate current gain range of 100 to 250 is required for NPN switching tasks. Ensure the design accommodates the 45 V collector-emitter voltage limit and the thermal constraints associated with the SOT23 package. Verify compatibility with standard surface-mount assembly processes for the TO-236AB footprint.
Part Context
This component belongs to the BC817 series of NPN general-purpose transistors produced by Nexperia. The series includes variants with different current gain ranges, specifically designated by suffixes indicating hFE bins. The BC817-16 variant provides a standardized gain profile suitable for common low-power electronic designs requiring reliable amplification or switching performance.
Replacement Considerations
Compatible substitutes within the same family include BC817-25 and BC817-40, which offer different DC current gain ranges. For direct pin-compatible replacement, verify that the alternative part meets the 45 V and 500 mA electrical requirements.
