Overview
The BC817-25T116 is an NPN general-purpose bipolar junction transistor manufactured by ROHM Semiconductor. It is housed in a SOT-23 surface-mount package and supports a maximum collector current of 500 mA with a collector-emitter voltage rating of 45 V. The device features a DC current gain (hFE) of 160 to 400 at 100 mA and 1 V, ensuring reliable amplification and switching performance. It operates within a temperature range of -55°C to +150°C and has a power dissipation capacity of 300 mW.
Feature Summary
- Integrated NPN structure optimized for high-current applications up to 500 mA
- Low voltage operation capability with a 45 V collector-emitter breakdown rating
- High DC current gain ranging from 160 to 400 for efficient signal amplification
- Surface-mount SOT-23 packaging designed for automated assembly processes
Applications
- General purpose switching circuits
- Amplifier stages in consumer electronics
- Interface driving applications
- Logic level translation buffers
Procurement Notes
Verify the specific suffix T116 against official ROHM documentation to confirm reel specifications and tape-and-reel dimensions. Ensure the component matches the required hFE binning for your circuit design. Cross-reference the datasheet revision date to confirm compliance with current environmental standards such as RoHS directives before finalizing procurement orders.
Selection Notes
Select this component when a compact NPN transistor with moderate current handling is required. The 45 V rating suits low-voltage logic systems. Compare the 160-400 hFE range against load requirements. Verify thermal management needs given the 300 mW dissipation limit in the small SOT-23 package. Ensure compatibility with existing PCB footprints.
Part Context
This part belongs to the BC817 series of general-purpose NPN transistors. It serves as a complement to PNP devices like the BC807. The T116 suffix typically indicates a specific tape-and-reel packaging format used for high-volume surface-mount production lines. It is widely used in portable devices due to its small form factor.
