The BC547 NPN Transistor is a general-purpose NPN bipolar junction transistor designed for low-to-medium current, low power, and medium voltage applications. Ideal for switching and amplification, it is commonly used in circuits such as relay drivers, LED drivers, and signal or audio amplifiers. With a maximum collector current of 800 mA and a collector-emitter voltage rating of 45 V, it delivers reliable performance in compact TO-92 packaging.
