2N2222 Description

Short technical summary and product information.

The 2N2222 is a versatile NPN bipolar junction transistor (BJT) manufactured by Texas Instruments, designed for both linear amplification and switching applications. It is presented in a standard TO-18 metal package, suitable for through-hole mounting.

Key electrical characteristics include a maximum collector current of 800 mA and a maximum collector-emitter voltage (VCEO) of 40 V for the 2N2222A variant. The transistor exhibits a DC current gain (hFE) ranging from 35 to 300 depending on the operating conditions and specific part number (2N2222 or 2N2222A). Its transition frequency (fT) is rated at a minimum of 250 MHz for the 2N2222 and 300 MHz for the 2N2222A.

Thermal management is supported by a junction-to-ambient thermal resistance of 350 K/W and a junction-to-case thermal resistance of 146 K/W. The device can dissipate up to 500 mW at 25°C ambient temperature or 1.2 W when the case temperature is at 25°C. Operating and storage temperatures are within the range of -65°C to +150°C.

This transistor is a reliable choice for various electronic circuits requiring efficient switching or amplification at moderate power levels.
