PN2222 vs 2N2222

2N2222 is the most common NPN bipolar junction transistor available in the market. Same as PN2222, it can be used for amplification of analog signals as well as switching applications. For most purposes, they are interchangeable.

 

But there are subtle differences between them.

 

Firstly, package, PN2222 is in a molded-epoxy TO-92; 2N2222 is in a TO-18 metal can.

 

Secondly, gain and leakage characteristics, PN2222A is properly a repackaging of 2N2222A, a better version of 2N2222.


Where to use PN2222 transistor

PN2222,  just like the generally used NPN transistor BC547. Nevertheless, there are two significant topographies which differentiate both of them. It can permit collector current up to 800mA and as well has power intemperance of 652mW.  Due to this, it is used for larger loads then BC547.

 

So if you are considering for an NPN transistor which can switch loads of large current user,  then PN2222 will be the right option for your industrial developments.


PN2222 Working Principle

Like other transistors, PN2222 can be used as an amplifier and switch.

 

Voltage crossways of base and emitter are six volts, so we have to apply these voltage crossways base and emitter to persuade a base current of the transistor.

 

This will change it to forward biasing and consequently completions the linking between collector and emitter. One important thing in this circuit is the base resistor which is a current preventive resistor. This resistor in the circuit is for limit the coming current which can damage the transistor. Its value can be found by the given equation.

RB = VBE / IB

To mark things modest, I have exposed a basic circuit of the transistor as a switch. In a real circuit, alterations must be vital. In this circuit, I supplied five volts to the base and 1K resistor to limit the current.

pn2222 working principle

Notice that in this circuit motor consumes around 500mA by the 12V supply source, meanwhile the PN2222 rating of the collector up to 800mA, which shows the importance that if we have BC547 in the circuit it would be damaged.


PN2222 Applications

  • It is used where higher current consumer loads in the circuit.

  • It is used in numerous swapping submissions.

  • It used to control the speed of different types of motors.

  • It used in inversion and rectification circuits.

  • It also used in Darlington pairs.

FAQ

  • What is a PN2222?

The PN2222 is a conjoint NPN bipolar junction transistor which is used for common persistence less power intensifying or swapping circuits applications. It is intended for low to intermediate current, squat power, intermediate voltage and can activate at a temperately higher speed.

  • How do you know if a transistor is NPN or PNP?

Depending on what is added to the silicon, it will be either N-type or P-type. An NPN transistor has a piece of P-type silicon (the base) sandwiched between two pieces of N-type (the collector and emitter). In a PNP transistor, the type of the layers are reversed.

  • What exactly does a transistor do?

transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. ... It is composed of semiconductor material usually with at least three terminals for connection to an external circuit.

  • What is 2N2222A transistor used for?

The 2N2222A is a common NPN bipolar junction transistor commonly used in general purpose low-power amplifying or switching applications. Featuring low to medium current needs and operable at moderately high speeds.
