Overview
The BC81825MTF is an NPN epitaxial silicon transistor manufactured by ON Semiconductor. It features a collector-emitter voltage of 25 V and a continuous collector current rating of 800 mA. The device is housed in a SOT-23 surface-mount package with three leads. Electrical characteristics include a DC current gain (hFE) range of 160 to 400 at IC = 100 mA, a collector-emitter saturation voltage of 0.7 V at IC = 500 mA, and a transition frequency of 100 MHz.
Feature Summary
- Designed for switching and amplifier applications
- Suitable for AF-driver stages and low power output stages
- Functions as the complement to the BC807/BC808 PNP transistor series
Applications
- Switching circuits
- Amplifier stages
- AF-driver stages
- Low power output stages
Procurement Notes
Verify that the ordering suffix indicates the correct hFE classification and packaging type. The suffix -25 specifies the DC current gain range of 160 to 400. The suffix -M denotes a matte finish package, while -TF indicates tape and reel packing. Confirm compliance with RoHS standards and lead-free requirements before procurement.
Selection Notes
Select this component when an NPN transistor with a 25 V collector-emitter voltage and 800 mA continuous current capability is required. Ensure the application operates within the specified junction temperature limits and thermal resistance constraints. Verify that the required DC current gain falls within the 160 to 400 range defined by the -25 suffix.
Part Context
This part belongs to the BC817/BC818 family of NPN epitaxial silicon transistors originally developed by Fairchild Semiconductor and now managed by ON Semiconductor following their integration. The product line provides general-purpose small-signal transistors suitable for various electronic designs requiring reliable amplification or switching performance.
Replacement Considerations
The BC817 series serves as a higher voltage alternative within the same family. Designers should verify pinout compatibility and ensure that the replacement part meets the specific voltage and current requirements of the circuit design.
