BC547ARLG

Single Bipolar Transistors Overview

The BC547ARLG is an NPN silicon epitaxial planar transistor from the onsemi BC546–BC548 series, housed in a TO-92 (CASE 29) package with bent leads for tape and reel shipping. It features a collector-emitter voltage of 45 Vdc, continuous collector current of 100 mAdc, and total device dissipation of 625 mW at 25°C ambient temperature. The component operates within a junction temperature range of -55°C to +150°C and includes Pb-Free packaging.

• Small-signal processing

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix 'RL1G' corresponds to the required bent lead tape and reel configuration. Confirm that the Pb-Free designation aligns with environmental compliance requirements for the target assembly process. Ensure the TO-92 package style matches the PCB footprint design constraints.

Single Bipolar Transistors Selection Notes

Select this component when a standard NPN small-signal transistor with 45V breakdown and 100mA current capability is required. The BC547A variant offers a minimum DC current gain of 110 at 2mA collector current. Consider the thermal resistance characteristics if operating near maximum power dissipation limits.

Single Bipolar Transistors Part Context

This part belongs to the BC546, BC547, and BC548 family of amplifier transistors manufactured by onsemi. These devices are designed for general-purpose amplification and switching tasks. The BC547 variant specifically provides a 45V collector-emitter voltage rating, distinguishing it from the higher-voltage BC546 and lower-voltage BC548 models.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include other BC547 variants such as BC547B or BC547C, provided their specific hFE ranges meet circuit requirements. Cross-manufacturer equivalents like the 2N3904 may be considered if pinout compatibility and electrical ratings are verified against the application needs.
