Single Bipolar Transistors datasheet and documents for BC549TFR

BC549TFR

Single Bipolar Transistors Overview

The BC549TFR is an NPN epitaxial silicon small-signal bipolar junction transistor manufactured by onsemi. It features a maximum collector-emitter voltage of 30V and a continuous collector current rating of 100mA. The device operates within a junction temperature range up to +150°C and dissipates up to 500mW of power. It utilizes a TO-92 package with kinked leads for through-hole mounting. The component exhibits a gain-bandwidth product of 300MHz, suitable for general-purpose amplification and switching applications in low-noise environments.

Single Bipolar Transistors Feature Summary

NPN epitaxial silicon construction designed for general-purpose signal processing
Low noise characteristics optimized for sensitive audio and RF circuits
Through-hole TO-92 packaging with kinked leads for secure board mounting

Single Bipolar Transistors Applications

General-purpose amplifier stages
Switching circuits requiring low noise performance
Audio pre-amplification systems

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'TFR' against official onsemi documentation to confirm tape-and-reel packaging specifications. Ensure the ordered part matches the required hFE binning if strict gain control is necessary. Cross-reference datasheets from authorized distributors to confirm RoHS compliance status and lead material composition prior to procurement.

Single Bipolar Transistors Selection Notes

Select this component when a standard NPN transistor with 30V breakdown and 100mA current capacity is required. The BC549 series offers complementary PNP counterparts (BC559) for push-pull configurations. Consider the thermal dissipation limits and ensure adequate heat sinking or airflow if operating near maximum ratings in enclosed designs.

Single Bipolar Transistors Part Context

This transistor belongs to the BC546–BC550 family of NPN epitaxial planar transistors. These devices are widely used as general-purpose switches and amplifiers. The BC549 variant specifically targets applications requiring moderate voltage handling and low noise performance, distinguishing it from higher voltage variants like the BC546.
