BC547ARL1

Single Bipolar Transistors Overview

The onsemi BC547ARL1 is an NPN epitaxial silicon general-purpose amplifier transistor housed in a TO-92 (TO-226AA) package. It features a maximum collector-emitter voltage of 45 V and a continuous collector current of 100 mA. The device offers a minimum DC current gain (hFE) of 110 at IC = 2.0 mA, with a transition frequency (fT) reaching 300 MHz. Total device dissipation is rated at 625 mW at 25°C ambient temperature. The component operates within a junction temperature range of -55°C to +150°C.

Single Bipolar Transistors Feature Summary

• NPN epitaxial silicon planar design for general-purpose amplification
• High current-gain bandwidth product supporting signal processing applications
• Lead-free packaging compliant with environmental directives

Single Bipolar Transistors Applications

• General-purpose small-signal amplification circuits
• Switching applications requiring low power consumption
• Audio pre-amplifier stages

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix RL1 corresponds to the Tape & Reel shipping configuration containing 2000 units per reel as documented in the manufacturer's Device Ordering Information table. Confirm that the part number includes the correct assembly location code 'A' and verify Pb-Free status if required by the Bill of Materials.

Single Bipolar Transistors Selection Notes

Select this component when a standard NPN small-signal transistor with a 45 V collector-emitter rating and 100 mA continuous current capability is required. The BC547 series provides complementary PNP devices (BC557 series) for push-pull configurations. Ensure the application environment remains within the specified thermal limits to maintain reliability.

Single Bipolar Transistors Part Context

The BC547ARL1 belongs to the BC546/547/548 family of NPN silicon transistors manufactured by onsemi. This series is widely utilized in consumer electronics and industrial control systems due to its standardized TO-92 form factor and predictable electrical characteristics across varying operating temperatures.

Single Bipolar Transistors Replacement Considerations

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