It was originally made in the TO-18 metal can as shown in the picture.

It is designed for low to medium current, low power, medium voltage, and can operate at moderately high speeds. The 2N2222 is a common NPN bipolar junction transistor (BJT) used for general purpose low-power amplifying or switching applications. It has three terminals named as: Emitter. It's a Bipolar junction transistor abbreviated as BJT. It is designed for high-speed switching applications at collector currents up to 500 MA and features useful current gain over a wide range of collector current, low leakage currents, and low saturation voltages.ĢN2222 is an NPN transistor, which means it has a single P doped layer embedded between two N doped layers.
