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

Views Read Edit View history. 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. Retrieved from ” https: From Wikipedia, the free encyclopedia.

Below is a table of the comparison and contrast of the transistors, with an explanation of dtaasheet everything in the table means below it. Wikimedia Commons has media related to 2N These really are extreme conditions.

So if you need to build an amplifier with a gain ofyou set up 3 transistor stages. Circuitbuilding do-it-yourself for Dummies. 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. The collector current is the amplified current that flows from the emitter terminal to the collector terminal to power on a load that may be connected to the transistor.

It often has a transition frequency of around 3. Nevertheless, a 2N and many other 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.

It was produced exclusively by the Czechoslovakian electronics company Tesla. Transistor Datzsheet looks at the current going from the base to the emitter. An MJ PNPwhich is also manufactured using the epitaxial process today, is a complementary transistor to the 2N If you need less than mA, the 2N or 2N will work.

The 2N is a common NPN bipolar junction transistor used for general-purpose low-power amplifying or switching applications. The robot builder’s bonanza 2nd ed. Modern successors to the 2N can be much more suitable in fast-switching circuits or high-end audio power amplifiers.

In the sheet above, it is also known as as transishor. 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 transstor smashing a whole bunch of letters and numbers together to make chip names sound ridiculous.

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.

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

In these ways, the 2N and the 2N are both identical. Now hFE and beta cannot be greater in value than allowed by the gain.

2N / BC / PN / 2N NPN Transistor – NTEAP

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: The higher-power 2N is a very similar NPN transistor that can safely switch three times as much current as the 2N This transistlr they are both controlled by current applied to the base and provide current amplification at the collector-emitter datasheeg.


The art of electronics 2nd ed. This page was last edited on 18 Octoberat Plus, currents this high need to be cautiously used because they can easily be lethal and can cause death. In simplicity, this really means that 40V is the maximum amount of trannsistor that the transistor can tolerate minus the voltage drop across the load connected to the collector.

Anyway so somehow they got to explaining how to find the DC current gain of a transistor based on its datasheet and such:. The historically-significant 2N was designed by Herb Meisel’s engineering group with RCA; it was the first multi-amp trxnsistor power transistor to sell for less than one dollar, and became an industry workhorse standard.

How they differ is that the 2N can handle greater operating collector current. In the sixties and early seventies, Philips produced similar devices encapsulated in TO-3 transistkr under the reference BDY20 described as being for “hifi” purposes and BDY38 although the BDY38 has lower voltage ratings than the 2N First explanation from mgburr and Lance: So the choice ultimately depends on how much current is needed.

In other projects Wikimedia Commons. 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.
