Since the early s, the 2N transistor has been heavily targeted by counterfeiters, who substitute much smaller silicon dies with lesser power ratings, use inferior mounting techniques, and transisttor the markings.
These really are extreme conditions. This means they are 2n394 controlled by current applied to the base and provide current amplification at the collector-emitter end.

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: It has a transition frequency of 2.
Retrieved 7 November Ttansistor 2N is a silicon NPN power transistor intended for general purpose applications.
The 2Nwith a TO-3 case has slightly lower gain but significantly higher maximum ratings W, Vceo, 16 Amps. Transistor Man looks at the current going from the base to the emitter. This page was last edited on 18 Octoberat Nevertheless, a 2N and many other power transistors originating from this era cannot be assumed to have great high-frequency performance and daasheet can be degradation of phase-shift and open-loop gain even within the audio frequency range.

Usually a 2N will suffice for most circuits, but if you need more than mA, then you should use a 2N instead. Build your own low-power transmitters: Commons category link from Wikidata. Retrieved from ” https: This means ttansistor 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 transiistor in order to operate. Variants with higher voltage ratings e.
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. The complementary 2m3094 transistor is 2N 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.
The higher-power 2N is a very similar NPN transistor that can safely switch three times as much current as the 2N An MJ PNPwhich is also manufactured using the epitaxial process today, is a complementary transistor to the 2N So in this way, the 2N does have superiority in that it can handle greater current.
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.
Other manufacturers around this time also would specify similar values e. Below is a table of the comparison and contrast of the transistors, with an explanation of what everything in the table means below it. Retrieved 31 October If you need less than mA, the 2N or 2N will work. A 2N can handle up to mA milliamperes of transistir flow from the emitter to collector terminal.
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. 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.

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 total power dissipation written P D in most American datasheets, P tot in European ones depends on the heatsink to which the 2N is connected.
