BC547ARL1G

Single Bipolar Transistors Overview

The BC547ARL1G is an NPN silicon epitaxial planar transistor manufactured by onsemi, designed for amplifier and switching applications. It features a collector-emitter voltage of 45 Vdc and a continuous collector current of 100 mAdc. The device operates within a junction temperature range of -55°C to +150°C. Electrical characteristics include a DC current gain (hFE) ranging from 110 to 800 depending on the specific grade, a transition frequency (fT) up to 300 MHz, and a maximum power dissipation of 625 mW at 25°C ambient temperature. It utilizes a TO-92 package.

Single Bipolar Transistors Procurement Notes

Verify the component authenticity against the official onsemi datasheet specifications. Confirm that the ordering suffix 'RL1G' corresponds to the Tape & Reel packaging format containing 2000 units per reel. Ensure the Pb-Free designation matches project environmental compliance requirements before finalizing procurement orders.

Single Bipolar Transistors Selection Notes

Select this component when a general-purpose NPN transistor with a 45V collector-emitter breakdown voltage is required. Consider the hFE binning options available within the BC547A/B/C series if specific DC current gain ranges are necessary for the circuit design. Verify thermal management needs against the 625 mW dissipation limit at 25°C ambient conditions.

Single Bipolar Transistors Part Context

This part belongs to the BC546/BC547/BC548 family of NPN silicon transistors. The BC547 variant specifically offers a 45V collector-emitter voltage rating, distinguishing it from the higher-voltage BC546 (65V) and lower-voltage BC548 (30V). All variants share similar physical packages and basic electrical structures while differing in breakdown voltage thresholds.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include BC547ARL1, BC547BRL1, and BC547CRL1 from onsemi, which share identical pinouts and mechanical dimensions but offer different DC current gain ranges.
