2N2222 STMicroelectronics NPN Switching Transistor

The 2N2222 from STMicroelectronics is a widely adopted NPN silicon transistor designed for general-purpose switching and signal amplification. This device typically supports collector-emitter voltages up to approximately 40V and is capable of handling moderate collector currents in compact circuit designs. The transistor is commonly supplied in a TO-18 metal can package, which offers strong thermal performance and mechanical reliability. Engineers frequently deploy the 2N2222 in switching interfaces, oscillator circuits, signal drivers, and small amplifier stages. Its fast switching characteristics and stable current gain make it suitable for both analog and digital electronics. Applications include communication hardware, instrumentation equipment, embedded control boards, and educational electronics platforms.
