2N2222A is a TO-92 packaged NPN BJT transistor that can be used in many types of general-purpose switching and amplification circuits. It is widely used for driving loads like relays, buzzers, small motors, and for signal amplification in low to medium power applications. For using it as a switch/driver, it can handle up to 600mA collector current with a maximum 40V collector-emitter voltage.
