Overview
The BC807-40,235 is a PNP general-purpose transistor manufactured by Nexperia in the SOT23 (TO-236AB) surface-mount 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 250 to 600 at -100 mA. Key electrical limits include a collector-base voltage of -50 V and an emitter-base voltage of -5 V. Total power dissipation reaches 250 mW in free air and 345 mW on a standard PCB footprint.
Feature Summary
- High current capability for demanding switching applications
- Three distinct current gain selections available within the series
- Small plastic surface-mounted package design
Applications
- General-purpose switching circuits
- Amplification stages
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact reel quantity and tape-and-reel specifications associated with the 235 designation. Ensure the component version matches the required automotive or non-automotive qualification status as defined in the latest product data sheet revision.
Selection Notes
Select this variant when a high-gain PNP transistor is required for low-voltage switching tasks. The BC807-40 provides a guaranteed minimum hFE of 250, distinguishing it from lower-gain series members. Confirm that the SOT23 package dimensions and thermal resistance values align with the target printed circuit board layout constraints.
Part Context
This component belongs to the BC807 series of PNP silicon transistors designed for general-purpose use. The series includes variants with different current gain ranges, such as BC807-16 and BC807-25. The BC807-40 specifically targets applications requiring higher amplification factors while maintaining compatibility with standard surface-mount assembly processes.
Replacement Considerations
The BC817-40 serves as the NPN complement within the same series. Other manufacturers produce functionally equivalent parts under similar naming conventions, though pinout and electrical tolerances must be verified against the original datasheet before substitution.
