The BC548 NPN General Purpose Transistor is a widely used NPN bipolar junction transistor ideal for general-purpose switching and amplification. Common in driver circuits and low-power audio or signal amplifiers, it operates reliably with a collector-emitter voltage of 30 V and a continuous collector current up to 100 mA. Featuring high current gain up to 800, it’s suitable for various electronic applications including Darlington pair configurations.
