2N2222 Transistor Pinout, Equivalent, Features, Uses & Applications

2N2222 Transistor Pinout is also one of the widely used in commercial appliances, educational and hobbyist projects. This transistor contains some of the best feature in its small package. For example the current collector of the transistor is 600mA, that it is use as a switch to drive maximum loads at a time in an electronic circuit. The maximum collector dissipation of this transistor is 625mW which makes this transistor ideal, it is used  in audio amplifier steps and as an output amplifier to drive small audio speaker. The maximum voltage of collector and emitter of the transistor is 40V, therefore the user can use it in any circuit operating under 40V DC. The pin configuration of 2N2222 Transistor Pinout.
