Product Overview
The 2N2222A 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, 600mA maximum collector current, and a minimum DC current gain of 100 at 150mA collector current. Its 250MHz transition frequency makes it suitable for compact signal-processing, interface, and low-voltage control circuits.
Packaged in a TO-92 through-hole package, the 2N2222A is suitable for prototype boards, general PCB designs, LED driving, relay control, signal amplification, and low-voltage transistor switching.
