Here you can see the amplifier circuit of 2N2222.

The temperature rating and power dissipation of 2n2222 are higher than PN2222 The packaging of 2N2222 is metallic while 2N222 is a plastic case.

Used in motor driver and switch circuits.

It is part of projects that need less power to operate.

Its uses in Inverters designs and projects.

It is used in RF circuits since it has the ability to handle high-frequency values.

It is the main part of the Darlington pair.

It is used in differnt types of robotics projects and embedded systems.

The main applications of PN2222 are explained here.

Here are main differences between PN2222 and PN2222A are explained.

The P2N2222 has a different order of pinouts than the metallic casing 2N2222, with its emitter and collector connections switched other plastic-case transistors also have different pinouts.

These two are the same transistor but there is a high value of maximum absolute for PN2222A.

Here are some points explained to find the difference between PN2222 and PN2222A.

Its operation is like the other types of BJT transistors. It is considered as part of RF applications it has a high value of transition frequency.

It has the ability to operate the load that has a value of ratings about six hundred milliampere.

The highest value of operating temperature is about minus fifty-five to one fifty centigrade.

The main features of PN2222 are explained here.

Collector: This pin provides the current to load and is attached to the load side.

Base: It is a control pin that regulates the transistor biasing and works as a tap on and off the device.

Like other transistors, it also has three pinout.

The second version comes with high values of maximum ratings than previous

It comes in two versions PN2222 and PN2222A.

It in form of a switch has the ability to operate a load value of about six hundred milliamperes so it is used to operate high-power LEDs, relays, motors, and high-power transistors.

The value of collector to emitter volts is about thirty volts with a transition frequency of about two fifty megahertz.

This current value makes it more effective than other To-92 packaging that has the highest value of collector current about 100mA to 200mA.

The highest collector curent for this transistor is about six hundred milliamperes.

It is the best option for electronic projects since comes in quality packing at less cost so it is a fine option for projects and electronic devices.
