The exact specifications depend on the manufacturer, case type, and variation. It is used in a variety of analog amplification and switching 2n222a datasheet. The JEDEC registration of a device number ensures particular rated values will be met by all parts offered under that number.

2n222a datasheet not to touch the transistor while testing it because temperature will change the voltage readings. In other dattasheet Wikimedia Commons. Billions of units have been manufactured over the past 45 years and there is continuing high volume annual production.

2n222a datasheet

2N Datasheet, Equivalent, Cross Reference Search. Transistor Catalog

The general specifications of the various variants 2n222a datasheet similar, with the biggest difference being the maximum allowable current and power dissipation. The 2N is considered a very common transistor, [1] 2n222a datasheet [3] and is used as an exemplar of 2n222a datasheet NPN transistor. Therefore, it is important to refer to the datasheet for the exact part number and manufacturer. Views Read Edit View history. Spehro Pefhany k 4 Commercial transistors Bipolar transistors.

They’re listed together because they’re complementary transistors.

This page was last edited on 3 Mayat Single transistors are also available in several different surface mount packages, and a number of manufacturers market surface mount packages that incorporate several 2Ntype transistors in one package as an array of transistors. To distinguish collector from emitter, you look at the voltage shown in the diode function with the one successful test that found the base.


Retrieved 26 March This is the picture of the datasheet for the pins: What do you think? All variations have a beta or 2n222a datasheet gain hFE of at least in optimal conditions. Wikimedia Commons has media related to 2N From Wikipedia, the free encyclopedia. It can be even worse, since the On Semi PN has the conventional pinout, despite being the same manufacturer and mostly same specifications: The BC is a low voltage, low current, general-purpose switching 2n222a datasheet in a TO package.

The 2N exhibits its forward gain beta peak at a lower current than the 2N, and is useful in amplifier applications with reduced Ic, e. The 2n222a datasheet is usually much higher when properly connected than when collector and emitter are swapped.

It looks like a “diode”. The 2n222a datasheet will show a diode 2n222a datasheet to both other pins, in only one polarity. Because it has attracted low-quality or spam answers that had to be removed, posting an answer 2n222a datasheet requires 10 reputation on this site the association bonus does not count. No other pin will show that. It is frequently used as a small-signal transistor, [4] [5] and it remains a small general purpose transistor [6] of enduring popularity.

The 2N is an NPN transistor that can only switch one-third the current of the 2N but has otherwise similar characteristics. 2n222a datasheet

Am I missing something here? Replacements for the 2N are commonly available now in the cheaper TO packaging, where it is known as the PN or P2N, which has similar specifications except for the lower maximum collector current.


Javier Loureiro 1 7 The 2N, 2N, and 2N devices, for example, which date back to 2n222a datasheet s datasheer have been improved, are still useful in new designs 2n222a datasheet are still popular for experimenters.

I have a simple circuit to send current to a brushless fan running at 12V 2n222a datasheet the high side, using a NPN transistor 2NA: It was originally made in the TO metal can as shown in the picture.

When I apply a voltage between the pin 1 to 3, as soon as the voltage rises over about 8V, the current starts to flow, even when 2n222a datasheet base has no voltage pulled down or floatingand the transistors gets pretty hot. Graf and William Sheets I don’t think 2n222a datasheet – throw it in the bin.

If it is to replace a shorted transistor, we will never know 2n222a datasheet both are the same ebc configuration between your new 2N and the old 2N You 2n222a datasheet have up to 3 types of configurations. Typical examples are the well known NPN and PNP industrial and military types, 2N and 2N, which dtasheet been used for over four decades and are still being used in many designs.

Most 2Ns have the orientation which your diagram shows, 2n222a datasheet if the flat side is facing you, the pins are E-B-C respectively. This is the pic of the transistor, as I understand 2n222a datasheet it should work, but it doesn’t it is always ‘on’ darasheet 12V between the collector and the emitter with the base floating.
