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 really are extreme conditions. An MJ PNPwhich is also manufactured using the epitaxial process today, is a complementary transistor to the 2N Plus, currents this high need to be cautiously used because they can easily be lethal and can cause death.

Per mgburr and Lancelot: Retrieved 31 October However, when you are dealing with electronics, unless you are in power electronics, you will pretty much never need amperage this high. Filed under beta hfe gain 2n tymkrs amplification transistor man transistors. Build your own low-power transmitters: First explanation from mgburr and Lance: KD are packaged in a TO-3 case style called T41 by Teslait is a 20 amp80 voltwatt power transistor.

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

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. It often has a transition transistro of around 3. The KD have higher power and higher current than 2N A good rule of thumb is to build it using the minimum beta value instead of the max:.


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 supplies. The 2N is a common NPN bipolar junction transistor used for general-purpose low-power amplifying or switching applications.

In the sheet above, it is also known as as hFE.

This means the 2N will suffice perfectly fine for these applications. The team of design, production, and applications engineers received RCA Electronic Components achievement awards in The art of electronics 2nd ed.

In other projects Wikimedia Commons. In these ways, the 2N and the 2N are both identical. It has a transition frequency of 2. A 2N can handle up to mA milliamperes of current flow from the emitter to collector terminal. Wikimedia Commons has media related to 2N Retrieved from ” https: It is designed for low current and powermedium voltageand can operate at moderately high speeds.

However, it doesn’t necessarily mean it’s the transistor that you should use. From Wikipedia, the free encyclopedia.

The 2Nwith a TO-3 case has slightly lower datashest but significantly higher maximum ratings W, Vceo, 16 Amps. RCA by had changed their specification to give 2.

So I asked folks what their favorite transistor was for audio applications and instead of getting 10 different kinds, a few of them agreed on the 2N spoilsports: Usually a 2N will suffice for most circuits, but if you need more than mA, then you should use a 2N instead.


Datasneet the higher frequency response has improved performance when used in audio amplifiers. This transistor is low-cost, widely available and sufficiently robust to be of use by experimenters and electronics hobbyists. The 2N is used very frequently in hobby electronics projects, including home-made ham radioscode-practice oscillators and as an interfacing device for microcontrollers.

Retrieved 7 November From Wikipedia, the free encyclopedia. These all normally require much less than mA to be powered on. With changes to semiconductor manufacturing technology, the original process became economically uncompetitive in the mids, and a similar device transistorr created using epitaxial base technology.

If you need greater than mA but less than 1A, then the 2N will be the one to use. Views Read Edit View history. 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 daatsheet breakdown rating, V CERand the Collector-Emitter Sustaining voltage, Datwsheet CEO susis given by ON Semiconductor.

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. This page was last edited on 22 Novemberat
