It is frequently used as a small-signal transistor, [4] [5] and it remains a small general purpose transistor [6] of enduring popularity. Other part numbers will have different parameters.

Thank you for your interest in this question. The JEDEC registration of a device number ensures particular rated values will be met by all parts offered under that datasyeet.

In other projects Wikimedia Commons. I don’t think so – throw it in the bin. Archived from the original on 14 April It looks like a “diode”. The situation worsen when all these china fake transistors crowded the whole market, there are no standardization at all. Since its initial product launch by Motorola at the IRE Convention, the 2N has dxtasheet the most widely used and universally recognized transistor of all time.


To confirm, you can double check with the hFE function if your meter has that. As the name suggests this resistor will limit the current flowing through the transistor to prevent it from damaging.

Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site the association bonus does not count.

JEDEC registered parameters include outline dimensions, small-signal current gaintransition frequencymaximum values for voltage withstand, current rating, power dissipation and temperature rating, and others, measured under standard test conditions. The exact specifications depend on the manufacturer, case type, and variation. Applications Can be used to switch high current upto mA loads It can also be used in the various switching applications.

This transistor like all can be used either as a switch or as an amplifier. Junkbots, bugbots, and bots on wheels: 2n2222a one important thing to notice is the Base resistor a. High frequency and microwave engineering. When base current is removed the transistor becomes fully off, this stage is called as the Cut-off Region and the Base Emitter voltage could be around mV.

Retrieved 26 March Eatasheet is the picture of the datasheet for the pins: To distinguish collector from emitter, you look at the voltage shown in the diode function with the one successful test that found the base.


The 2N is an NPN transistor that can only switch one-third the current of the 2N but has otherwise similar characteristics. Submitted by webmaster on 11 December This page was last edited on 25 Octoberat Single transistors are also available in several different surface mount packages, and a number of manufacturers 2n222w surface mount packages that incorporate several 2Ntype transistors in one package as an array of transistors. No other pin will show that.

In actual circuit modifications might be required. You can have up to 3 types of configurations. Complete Technical Details can be found at the 2NA datasheet given at the end of this page.

Spehro Pefhany k 4 Wikimedia Commons has media related to 2N Try not to touch the transistor while testing it because temperature dztasheet change the voltage readings.

I am trying to figure out what is going on here.

But there are two important features that distinguish both. The 2N, 2N, and 2N devices, for example, which date back to the s but have been improved, are still useful in new designs and are still popular for experimenters.
