If you use 10kΩ LED will not glow when you turn on the switch due to low current passing through the LED.By mistake, 10kΩ used as a current limiting resistor with an LED. Connect an LED with an emitter terminal through a 220-ohm resistor.5 volts with collector terminal through 220ohm resistor. In this example circuit, we attach a push-button with a base terminal.

And their biggest difference is their pinout, as showned in the figure below: As a replacements for the 2N2222, they are commonly available in the cheaper TO-92 packaging, which has similar specifications except for the lower maximum collector current. Speaking of which, there is another ic that similar and easy to confused with 2N2222, that is PN2222/P2N2222. Down below is the feature differences between them. Like 2N2222, 2N2222A is also an NPN transistor.

Switching many loads at the same time (Thanks to its 600mA output in a small TO-92 package).

How to Safely Long Run 2N2222 in a Circuit

It is most common in the market due to the cost efficiency and the smaller size. The major functional area of 2N-2222 is enclosed in a TO-18 package. It can be used for amplification of analog signals as well as switching applications. Hope this blog is helpful to you.ĢN2222 is the most common NPN bipolar junction transistor available in the market. In today's blog, we are going to discuss 2n2222's pinout, applications, equivalents, example circuits and where and how to use this device, etc.
