Single Bipolar Transistors datasheet and documents for BC549TF

BC549TF

Single Bipolar Transistors Overview

The onsemi BC549TF is an NPN epitaxial silicon transistor housed in a TO-92-3 Kinked Lead package. It supports a maximum DC collector current of 100 mA and features a collector-emitter voltage (VCEO) of 30 V and a collector-base voltage (VCBO) of 30 V. The device has a power dissipation rating of 500 mW, a gain-bandwidth product (fT) of 300 MHz, and a maximum operating temperature of +150°C.

Single Bipolar Transistors Feature Summary

Low noise characteristics suitable for sensitive signal processing applications
RoHS compliant lead-free construction

Single Bipolar Transistors Applications

General purpose amplifiers
Switching circuits
Audio pre-amplification stages

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'TF' against the official onsemi datasheet to confirm packaging details such as reel or cut tape specifications. Ensure the component matches the required hFE binning grade if precise gain control is necessary for the design. Confirm RoHS compliance status directly from the manufacturer's documentation prior to integration.

Single Bipolar Transistors Selection Notes

Select this component when a low-noise NPN transistor with a 30 V breakdown voltage is required. The 300 MHz gain-bandwidth product supports high-frequency operation. Verify that the TO-92 through-hole package fits the board layout constraints and that the 500 mW power dissipation rating meets thermal requirements.

Single Bipolar Transistors Part Context

This part belongs to the BC546–BC550 series of NPN transistors. These devices are widely used in consumer electronics and industrial equipment. The BC549 variant specifically offers low noise performance compared to standard variants like the BC547, making it distinct within the family for audio and RF applications.
