BC848BMTF

Overview

The BC848BMTF is a single NPN bipolar junction transistor manufactured by onsemi, housed in an SOT-23-3 surface-mount package. It features a maximum collector-emitter voltage of 30 V and a continuous collector current rating of 100 mA. The device has a power dissipation capacity of 310 mW and a transition frequency of 300 MHz. DC current gain (hFE) is guaranteed to be at least 200 when tested at 2 mA collector current and 5 V collector-emitter voltage. The saturation voltage is specified as a maximum of 600 mV under conditions of 5 mA base current and 100 mA collector current.

Feature Summary

• Single NPN epitaxial silicon planar design for general-purpose amplification
• High DC current gain with a minimum specification of 200 at low bias currents
• Surface-mount construction in a compact SOT-23-3 package for automated assembly

Applications

• General purpose amplifier circuits
• Switching applications requiring low voltage operation
• Signal conditioning in consumer electronics

Procurement Notes

Verify the specific manufacturer part number BC848BMTF against official onsemi documentation to confirm pinout compatibility and electrical tolerances. Ensure that the SOT-23-3 package dimensions match the target PCB footprint. Confirm that the component meets required environmental standards such as RoHS compliance before finalizing procurement specifications.

Selection Notes

Select this component when a small-signal NPN transistor with moderate current handling and high gain is required in a compact surface-mount form factor. The 30 V breakdown voltage suits low-voltage logic interfaces. Compare the 310 mW power dissipation limit against thermal constraints in the final enclosure to ensure reliable operation under continuous load conditions.

Part Context

This component belongs to the BC848 series of general-purpose NPN transistors produced by onsemi. The BC848 family is widely utilized in electronic designs for basic switching and amplification tasks. The MT suffix typically denotes a specific tape and reel packaging configuration intended for high-volume surface-mount manufacturing processes.

Replacement Considerations

Direct substitutes include other manufacturers' BC848B variants in SOT-23 packages, such as those from Diotec or Panjit. Verify that alternative parts maintain identical pin configurations and meet or exceed the 30 V voltage and 100 mA current ratings.
