2N2222A Description
The 2N2222A is a NPN transistor, so the collector and emitter will remain open (reverse bias) while the footing remains on (reverse bias), while the collector and emitter will be closed (forward bias) when a signal is provided to the footing. The gain value of 2N2222A is from 110 to 800, which determines the amplification ability of the transistor.
2N2222A Features

2N2222A Applications
This kind of transistor is mainly used for amplifying current
This transistor can be used as a switch for automatically switch ON/OFF any appliances.
It is used for PWM due to its quick response
Because of its fast response time, it can be used for pulse width modulation.
It is typically used in automation & embedded projects.
Audio Preamplifiers
Sensor Circuits
Audio Amplifier Stages
Used to switch several loads simultaneously
RF Circuits
Darlington Pairs
These transistors are used in Motor drive circuits like VFD or variable frequency drives.
Used in Rectifier Circuits & DC Inverters
It is used as an amplifier to amplify voltage, current & power.
Darlington pair transistors are used for attaining the maximum current from the emitter terminal to the collector.
As compared to the normal NPN BC547 transistor, the 2N2222 is extremely similar, but 2N2222 allows 800mA of collector current & also 652mW of power dissipation which can be utilized for driving larger loads as compared toBC547.
So, the 2N2222 transistor is the best choice for switching high current loads
