2N2222 Metal Can Transistor Explained / Description:

2N2222 is a very famous transistor and also widely used in electronics applications whether it’s a commercial or educational application. The transistor is available in many different part numbers and which are 2N2222, 2N2222A, PN2222, PN2222A and all the part numbers are slightly different from each other in specs. Also these transistors are available two different packages which are TO-92 and TO-18, but in this post we are going to discuss 2N2222 TO-18 metal can transistor in detail.

The transistor performs well in both regions which are switching and amplification. When looking at its switching capabilities it can drive load of upto 0.8A or 800mA a little bit higher than its plastic version which has 500mA to 600mA collector current or current load driving capability. When looking at its collector to emitter voltage or voltage load voltage capabilities it maximum collector to emitter voltage is 30V which means it can drive load voltage of upto 30V. Moreover it has an also high speed switching capability which makes it ideal to use in applications in which high speed switching is crucial.

More over the maximum DC current gain is 50 to 300 and the maximum transition frequency is upto 300MHz.

Where We Can Use It & How to Use:

2N2222 is a general purpose transistor with lot of capabilities in a small package. When working as an amplifier it can be used in audio amplification circuits, audio preamplification circuits and any type of small signal amplification in electronic application. Other than that it can also be used as a switch to drive load of upto 800mA. The maximum transition frequency is UP to 300MHz due to which this transistor can also be used in radio and RF circuits under 300MHz.

PNP Complementary:

PNP Complementary of 2N2222 is 2N2907

Replacement and Equivalent:

2N2219, 2N1613, 2N2218, 2N2792

Applications:

FM Radios

FM Senders

Audio premamplifiers

Audio amplifiers

Normal and high speed switching

Safe Operating Guidelines / Absolute Maximum Ratings:

Understanding the absolute maximum ratings of a component is also very important and using a component on its absolute maximum ratings is also not suggested by its manufacturers therefore we suggest using a component atleast 20% below from its absolute maximum ratings. The maximum collector current of the transistor is 800mA therefore do not drive load of more than 640mA. The maximum collector to emitter voltage is 30 so do not drive load of more than 24V. Use a suitable heatsink with the transistor and always store and operate the transistor at temperature above -65 degree centigrade and below 200 degree centigrade.
