Description
The BC547 is a widely used NPN bipolar junction transistor (BJT) designed for low-current, medium-voltage, and low-power switching or amplification tasks. It operates with a maximum collector current of 100 mA and a collector-emitter voltage rating of 45V. With a DC current gain (hFE) ranging from 110 to 800, it is suitable for signal amplification, switching applications, and interfacing with microcontrollers. Commonly found in hobby electronics, consumer devices, and control circuits, the BC547 is available in a TO-92 package, making it compact and easy to integrate into breadboards and PCB designs.
