BC549C

Single Bipolar Transistors Overview

The onsemi BC549C is an NPN epitaxial silicon planar transistor housed in a TO-92 (SPT) through-hole package. It features a maximum DC collector current of 100 mA and a collector-emitter voltage rating of 30 V. The device has a maximum power dissipation of 500 mW and operates up to a junction temperature of +150 °C. The minimum DC current gain (hFE) for the 'C' suffix is 640 at IC=2mA and VCE=5V. The transition frequency is typically 300 MHz.

Single Bipolar Transistors Feature Summary

High DC current gain suitable for sensitive amplification applications
Low noise characteristics optimized for audio signal processing
Complementary PNP counterpart available within the same series

Single Bipolar Transistors Applications

General-purpose amplifier circuits
Audio pre-amplifier stages
Switching applications requiring low leakage

Single Bipolar Transistors Procurement Notes

Verify the manufacturer origin, as this component is produced by multiple vendors including NXP and Diotec. Confirm the specific hFE binning requirements match the circuit design needs. Ensure the package type matches the PCB footprint. Check RoHS compliance status if required by project specifications.

Single Bipolar Transistors Selection Notes

Select based on the required current gain range; the 'C' suffix indicates high gain compared to 'A' or 'B'. Consider thermal management due to the 500 mW power limit. Verify compatibility with complementary PNP devices if push-pull configurations are used. Ensure voltage ratings meet the peak operating conditions of the target circuit.

Single Bipolar Transistors Part Context

Part of the BC546-BC550 series of general-purpose NPN transistors. Designed for low-power switching and amplification tasks. Commonly used in consumer electronics and industrial control systems where small signal handling is required.
