BC558 is a TO-92 packaged PNP BJT transistor that can be used in many kinds of general-purpose low-power electronic circuits. It is commonly used for signal amplification and switching applications like sensor circuits, audio stages, and small load control. For using it as a switch/driver, it can typically handle up to 100mA collector current with a maximum 30V collector-emitter voltage.
