BC548CG

Single Bipolar Transistors Overview

The onsemi BC548CG is an NPN silicon planar epitaxial transistor housed in a TO-92 (CASE 29) lead-free package. It features a collector-emitter voltage of 30 Vdc, continuous collector current of 100 mAdc, and total device dissipation of 625 mW at 25°C ambient temperature. The 'C' suffix designates a high DC current gain range of 420 to 800 at IC=10mA/VCE=5V or 450 to 800 at IC=2mA/VCE=5V. Operating junction temperatures span from -55°C to +150°C.

Single Bipolar Transistors Feature Summary

• NPN silicon planar epitaxial construction for reliable small-signal amplification
• High DC current gain configuration suitable for sensitive signal processing
• Lead-free packaging compliant with environmental directives

Single Bipolar Transistors Applications

• General-purpose amplifier circuits
• Low-noise audio pre-amplification stages
• Electronic switching applications

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix 'G' confirms the Pb-Free status as documented in the onsemi datasheet. Confirm the package style matches the required pinout orientation (Style 17: Collector, Base, Emitter). Ensure the component meets the specified thermal resistance limits for your application environment.

Single Bipolar Transistors Selection Notes

Select this variant when a high current gain (hFE 420-800) is required for low-level signal amplification. Compare against BC548B if lower gain is acceptable. Verify that the 30V collector-emitter rating aligns with the circuit's maximum operating voltage requirements.

Single Bipolar Transistors Part Context

This component belongs to the BC546/BC547/BC548 series of NPN general-purpose transistors manufactured by onsemi. The BC548 variant specifically offers a 30V breakdown voltage, distinguishing it from the higher-voltage BC546 and BC547 models within the same family.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include other manufacturers' BC548CG parts or equivalent NPN transistors with matching 30V VCEO, 100mA IC, and high hFE gain specifications in a TO-92 package.
