The BC557 is a general-purpose transistor that may be utilised in electrical circuits as an amplifier or a switch. This transistor's hFE ratings vary from 125 to 800, making it perfect for use as an amplifier in electrical circuits such as audio signal amplification. The PNP transistor is a type of transistor in which one n-type material is doped with two p-type materials. It is a device that is controlled by the current. Both the emitter and collector currents were controlled by the small amount of base current.
