From Datashewt, the free encyclopedia. RCA by had changed their specification to give 2. Filed under beta hfe gain 2n tymkrs amplification transistor man transistors.

If you need greater than mA but less than 1A, then the 2N will be the one to use. The 2N and the 2N are 2 of the most popular NPN bipolar junction transistors in the electronics market. Comparing transistors isn’t extensive, as there are only a few very useful parameters that matter. The 2N remains very popular as a series pass transistor in linear power supplies and is still used in for medium- current and high- power circuits generally, including low frequency power converters although its use in audio power amplifiers and DC-to-AC inverters is now less common and its use in higher frequency switch-mode applications never was very practical.

Trznsistor from ” tfansistor In other projects Wikimedia Commons. In the sheet above, it is also known as as hFE. This page was last edited on tranisstor Novemberat Typical components that may require a transistor in order to be driven are motors, buzzers, solenoids, and high-power LEDs.

In case you’re curious about which to use, or which one is better or superior than the other, in this article, we compare and contrast the 2 transistors. A good rule of thumb is to build it using the minimum beta value instead of the max:.


The frequency at which gain begins to drop off may be much lower, see below. The robot builder’s bonanza 2nd ed. The 2Nwith a TO-3 case has slightly lower gain but significantly higher maximum ratings W, Vceo, 16 Amps. In simplicity, this really means that 40V is the maximum amount of voltage that the transistor can tolerate minus the voltage drop across the load connected to the collector.

Datashheet 2N is a much lower power version of the 2N, rated at 25 W55 V transistkr 4 Abut became almost obsolete about the late s when many TO devices were withdrawn from mainstream manufacturers’s lists.

In these ways, the 2N and the 2N are both identical.

Beta? Hfe? Gain? 2Ns! I think its transistor

The complementary PNP transistor datssheet 2N By using this site, you agree to the Terms of Use and Privacy Policy. Usually a 2N will suffice for most circuits, but if you need more than mA, then you should use a 2N instead. The historically-significant 2N was designed by Herb Meisel’s engineering group with RCA; it was the first multi-amp silicon power transistor to sell for less than one dollar, and became an industry workhorse standard.

Commons category link from Wikidata. This means the 2N will suffice perfectly fine for these applications. So in this way, the 2N does have superiority in that it can handle greater current. Also the higher frequency response tranisstor improved performance datsheet used in audio amplifiers. Circuitbuilding do-it-yourself for Dummies.

2N3904 vs 2N2222

This page was last edited on 18 Octoberat Other manufacturers around this time also would specify similar values e. Sometimes the V CBO breakdown voltage the maximum voltage between collector and base, with the emitter open, an rtansistor arrangement in practical circuits is given as the only voltage rating, which can cause confusion. So the choice ultimately depends on how much current is needed.

And if you need greater current, the TIP can handle up to 15A. Now hFE and beta cannot be greater in value than allowed by the gain.


A 2N can handle up to 5 times that amount, since it can handle up to 1A ampere of current flow from the emitter to collector to power on a load. Variants with higher voltage ratings e. It often has a transition frequency of around 3.

And if you need greater than 1A at the output, then a darlington transistor such as the TIP transistor can be used, which can handle up to 5A of amplified current.

But, if you wanted to power several of them, for instance, you may need more current, what you would get from the 2N, up to 1A. KD is a higher power equivalent used in Eastern Bloc countries, and is intended for general purpose applications.

Retrieved from ” https: However, it doesn’t necessarily mean it’s the transistor that you should use. Graf; William Sheets It is designed for low current and powermedium voltageand can operate at moderately high speeds.

It was second sourced by other manufacturers; Texas Instruments listed a single-diffused mesa version of the device in an August datasheet. Commons category link is on Wikidata. Although the original 2N went into decline relative to epitaxial-base transistors because of high manufacturing costs, the epitaxial-base version continued to be used in both linear amplifiers and switching tranaistor. It is by now unlikely to actually obtain a genuine 2N transistor when using popular sales platforms such as Amazon or Ebay; classic electronics distributors are mostly still able to properly source them.

So a bunch of the folks were talking about engineering and electronics and the like in our irc room and I got to talking about how engineers love smashing a whole bunch of letters and numbers together to make chip names sound ridiculous.

How they differ is that the 2N can handle greater operating collector current.
