BC548CTFR

Single Bipolar Transistors Overview

The BC548CTFR is an NPN epitaxial silicon planar transistor from the onsemi BC546-BC550 series, housed in a lead-free TO-92 package. It features a collector-emitter voltage of 30V and a continuous collector current of 100mA with 500mW power dissipation. The 'C' suffix indicates a high DC current gain (hFE) range of 420 to 800 at VCE=5V and IC=2mA. The 'TFR' suffix denotes tape-and-reel packaging for automated assembly. Transition frequency reaches 300MHz, supporting small-signal amplification.

Single Bipolar Transistors Procurement Notes

Verify the specific manufacturer datasheet for the BC548CTFR to confirm exact electrical tolerances and thermal characteristics. Ensure the ordering code matches the required gain bin and packaging format. Cross-reference RoHS compliance status with the latest regulatory updates. Confirm pinout orientation against standard TO-92 specifications during integration.

Single Bipolar Transistors Selection Notes

Select this component when high current gain is critical for low-level signal processing. The tape-and-reel format suits high-volume automated production lines. Compare hFE ranges against circuit requirements to ensure adequate amplification without excessive biasing adjustments. Consider the complementary BC558CTFR for PNP applications requiring matched performance characteristics.
