PN2222A NPN bipolar junction transistor (NOS)

The PN2222A is a widely used NPN bipolar junction transistor housed in a cost-effective TO-92 plastic package. It offers a collector-emitter voltage of 40 V, collector-base voltage of 75 V, and can handle continuous collector currents between 600 mA and 800 mA, depending on the manufacturer. With a power dissipation rating of 625 mW and a transition frequency of 300 MHz, it is suitable for general-purpose amplification and switching applications requiring moderate power and frequency response. Its DC current gain provides reliable amplification performance in diverse electronic circuits.
