Overview
The Nexperia BC817-25,235 is an NPN general-purpose transistor housed in a small SOT23 (TO-236AB) surface-mount plastic package. It supports a maximum collector current of 500 mA and a collector-emitter voltage of 45 V. The device offers a DC current gain range of 160 to 400 at 100 mA. Key electrical limits include a collector-base voltage of 50 V, an emitter-base voltage of 5 V, and a peak collector current of 1 A for single pulses up to 1 ms. Total power dissipation reaches 250 mW at 25 °C ambient temperature.
Feature Summary
- High current 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 packaging details and manufacturing site codes. Confirm that the component meets RoHS compliance standards required for your assembly process. Ensure the selected variant aligns with your thermal management requirements given the SOT23 package constraints.
Selection Notes
Select this part when a compact NPN transistor with moderate current handling is required. The BC817-25 variant provides a balanced current gain profile compared to other series options. Consider the SOT23 footprint compatibility during PCB layout planning to ensure proper thermal dissipation and soldering reliability.
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 ranges to suit various design needs. The BC817-25 specifically targets applications requiring a mid-range gain specification while maintaining the standard 45 V and 500 mA ratings common across the family.
Replacement Considerations
The BC807-25 serves as the PNP complement within the same series. Other BC817 variants like BC817-16 or BC817-40 may be considered if different current gain thresholds are needed, provided they fit the existing circuit design constraints.
