BC547ARL

Single Bipolar Transistors Overview

The onsemi BC547ARL is an NPN silicon epitaxial planar transistor designed for general-purpose amplifier and switching applications. It operates within a collector-emitter voltage of 45 Vdc and supports a continuous collector current of 100 mAdc. The device features a DC current gain (hFE) ranging from 110 to 800 at IC = 2.0 mA, with a minimum of 110 at IC = 10 mA. It exhibits a current-gain-bandwidth product (fT) up to 300 MHz and maintains a total device dissipation of 625 mW at 25°C ambient temperature.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix 'RL' corresponds to the Tape & Reel packaging configuration as defined in the official datasheet. Confirm that the component meets Pb-Free requirements if environmental compliance is mandatory for the assembly process. Ensure the selected variant matches the required hFE binning specifications for the intended circuit performance.

Single Bipolar Transistors Selection Notes

Select this component when a high-gain NPN transistor is required for low-power amplification tasks. The BC547 series offers complementary PNP devices (BC556-558) for push-pull configurations. Consider the thermal resistance characteristics and operating temperature range (-55°C to +150°C) to ensure reliability under varying environmental conditions.

Single Bipolar Transistors Part Context

The BC547ARL belongs to the BC546/547/548 family of NPN silicon transistors manufactured by onsemi. These components are widely utilized in consumer electronics and industrial control systems due to their versatility and robust electrical characteristics. The 'A' designation indicates a specific DC current gain binning, while 'RL' denotes the tape and reel shipping format.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include other BC547 variants with matching gain bins or equivalent general-purpose NPN transistors such as MMBT100. Verify pinout compatibility (Collector-Base-Emitter Style 17) and thermal ratings before implementation.
