BC548CTF

Single Bipolar Transistors Overview

The onsemi BC548CTF is an NPN epitaxial silicon bipolar junction transistor designed for switching and amplifier applications. It features a TO-92 through-hole package with formed leads. Key electrical ratings include a maximum collector-emitter voltage of 30V, a maximum collector-base voltage of 30V, and a maximum emitter-base voltage of 5V. The device supports a continuous DC collector current of 100mA and a power dissipation of 500mW. It offers a minimum DC current gain (hFE) of 420 at 2mA and 5V, with a transition frequency of 300MHz. Operating temperatures range from -55°C to +150°C.

Single Bipolar Transistors Feature Summary

• Complementary pairing with BC558 series PNP transistors

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'TF' against official manufacturer documentation to confirm tape-and-reel packaging and exact binning specifications. Ensure compatibility with existing PCB footprints for TO-92-3 packages. Confirm RoHS compliance status and SVHC declarations for the specific manufacturing batch prior to integration into final assemblies.

Single Bipolar Transistors Selection Notes

Select this component when high current gain is required for low-level signal processing. The 30V rating limits suitability for high-voltage applications compared to BC546 variants. Consider the 300MHz transition frequency for RF considerations. Verify that the 500mW power dissipation aligns with thermal management capabilities in the target enclosure design.

Single Bipolar Transistors Part Context

The BC548CTF belongs to the BC546-BC550 series of general-purpose NPN transistors manufactured by onsemi. This series provides complementary PNP options in the BC556-BC560 lineup. The BC548 variant specifically targets applications requiring moderate voltage handling and high gain, distinguishing it from higher voltage or lower noise variants within the broader family.

Single Bipolar Transistors Replacement Considerations

BC548CTA and BC548BTA are verified substitutes within the same series offering similar electrical characteristics. Cross-manufacturer equivalents such as those from Diotec Semiconductor may be considered if pinout and parameter tolerances match the original design requirements.
