With changes to semiconductor manufacturing tdansistor, the original process became economically uncompetitive in the mids, and a similar device was created using epitaxial base technology. Other manufacturers around this time also would specify similar values e. It has a transition frequency of 2. Retrieved from ” https: First explanation from mgburr and Lance: The robot builder’s bonanza 2nd ed.

Commons category link from Wikidata. Plus, currents this high need to be cautiously used because they can easily be lethal and can cause death.

2N3904 vs 2N2222

If tdansistor need greater than mA but less than 1A, then the 2N will be the one to use. In the sixties and early seventies, Philips produced similar devices encapsulated in TO-3 packages under the reference BDY20 described as dxtasheet for “hifi” purposes and BDY38 although the BDY38 has lower voltage ratings than the 2N The complementary PNP transistor is 2N Archived from the original on It was introduced in the early s by RCA using a hometaxial power transistor process, transitioned to an epitaxial base in the mids.

The exact performance characteristics depend on the manufacturer and date; before the move to the epitaxial base version in the mids the f T could be as low as 0.

The collector current is the amplified current that flows from the emitter terminal to the collector terminal to datasheeh on a load that may be connected to the transistor. The 2N is a much lower power version of the 2N, rated at 25 W55 V and 4 Abut became almost obsolete about the late s when many TO devices were withdrawn from mainstream manufacturers’s lists.


Build your own low-power transmitters: This transistor is low-cost, widely available and sufficiently robust to be of use by experimenters and electronics hobbyists.

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

It is used in a variety of analog amplification and switching applications. KD datazheet packaged in a TO-3 case style called T41 by Teslait is a 20 amp80 voltwatt power transistor. Wikimedia Commons has media related to 2N This wouldn’t be acceptable, since it exceeds the maximum V CEO. Nevertheless, a 2N and many fatasheet power transistors originating from this era cannot be assumed to have great high-frequency performance and there can be degradation of phase-shift and open-loop gain even within the audio frequency range.

And if you need greater than 1A datwsheet the output, then a darlington transistor such as the TIP transistor can be used, which can handle up to 5A of amplified current. However, when you are dealing with electronics, unless you are in power electronics, you will pretty much never need amperage this high. These really are extreme conditions.

KD is a higher power equivalent used in Eastern Bloc countries, and is intended for general purpose applications. From Wikipedia, the free encyclopedia. In other projects Wikimedia Commons. Transistor Man looks at the current going from the base to the emitter.

This page was last edited on 22 Novemberat Per mgburr and Lancelot: This means that in a circuit, voltage and current are biased to them the same exact way- they both must receive positive voltage to the base and collector terminals in order to operate.

In the sheet above, it is also known as as hFE. Circuitbuilding do-it-yourself for Dummies. If you need less than mA, the 2N or 2N will work. So the choice ultimately depends on how much current is needed. In these ways, the 2N and the 2N are both identical. Retrieved from ” https: Modern 2N datasheets often, but not always, specify f T of 2. Although the original 2N went into decline relative to epitaxial-base transistors because of high manufacturing costs, the epitaxial-base version continued to be transiator in both linear amplifiers and switching supplies.


The 2N is used datasheett frequently in hobby electronics projects, including home-made ham radioscode-practice oscillators and as an interfacing device for microcontrollers.

Comparing transistors isn’t extensive, as there are only a few very useful parameters that matter. With an “infinite” heatsink, that is: So in this way, the 2N does have superiority in that it can handle greater current. The 2N and the 2N are 2 of the most popular NPN bipolar junction transistors in the electronics market.

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. These all normally datasueet much less than mA to be powered on. Motors, for example, typically require in the range of about 75mA to power on. The maximum collector-to-emitter voltage for the 2N, like other transistors, depends on the resistance path the external circuit provides between the base and emitter of the transistor; with ohms a 70 volt breakdown rating, V CERand the Collector-Emitter Sustaining voltage, V CEO susis given by ON Semiconductor.

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.
