2N2222A Description

Short technical summary and product information.

The 2N2222A is a general-purpose NPN bipolar junction transistor manufactured by STMicroelectronics. It features a minimum collector-emitter breakdown voltage of 40V and a maximum collector current of 600mA, making it suitable for a wide range of switching and amplification applications.

 

With a minimum DC current gain (hFE) of 100 at 150mA and a typical transition frequency of 300 MHz, this transistor offers reliable performance in low-to-medium frequency circuits. The maximum collector-emitter saturation voltage is 1V at 50mA base current and 150mA collector current. Additional characteristics include a maximum collector-base capacitance of 8 pF, a rise time of 25 ns, and a fall time of 60 ns.

 

The device can dissipate up to 500 mW of power and operates with a maximum junction temperature of 175°C. The 2N2222A is housed in a TO-18 metal can package (TO-206AA / TO-18-3) designed for through-hole mounting.
