What is PN2222?

This is 40V, 600mA, NPN switching transistor in a TO-92, SOT54 plastic package.

The PN2222 is a bipolar junction transistor (BJT) that is commonly used in electronic circuits for amplification, switching, and other functions. It is a low-power NPN transistor that has a maximum collector current rating of 600mA, a maximum collector-emitter voltage rating of 30V, and a maximum power dissipation of 625mW.

The transistor is housed in a TO-92 package and has three pins: the emitter, the base, and the collector. The emitter is connected to the negative or ground side of the circuit, while the collector is connected to the positive or supply side. The base is the control pin that allows current to flow between the emitter and collector.

The PN2222 transistor can be used in a variety of electronic circuits, such as amplifiers, oscillators, and switching circuits. In amplifier circuits, it can be used to amplify weak signals, while in switching circuits, it can be used to turn on and off loads such as motors, lights, and relays.
