Product Overview
The 2N2222 is an NPN bipolar junction transistor designed for general-purpose switching, driver, and small-signal amplification applications. It features a 40V collector-emitter voltage rating, up to 1A collector current, and 625mW power dissipation. Its combination of useful current capability and general-purpose gain characteristics makes it suitable for discrete control, interface, and low-voltage driver circuits.
Packaged in a TO-92 through-hole package, this version is suitable for prototype boards, general PCB designs, LED driving, transistor switching, signal amplification, and other low-power control applications.
