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 transisstor order to operate. Comparing transistors isn’t extensive, as there are only a few very useful parameters that matter.

In these ways, the 2N and the 2N are both identical. In other projects Wikimedia Commons.

2N3904 vs 2N2222

Commons category link from Wikidata. When figuring out DC current gain, the beta value is part of the formula. The complementary PNP transistor is 2N 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.

Usually a 2N will suffice for most circuits, but if you need more than mA, then you should use a 2N instead. Motors, for example, typically require in the range of about 75mA to power on. The 2Nwith a TO-3 case has slightly lower gain but significantly higher maximum ratings W, Vceo, 16 Amps. 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.


The 2N is used very frequently in hobby electronics projects, including home-made ham radioscode-practice oscillators and as an interfacing device for microcontrollers. RCA by had changed their specification to give 2. 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.

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.

Filed under beta hfe gain 2n tymkrs amplification transistor man transistors. 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.

Per mgburr and Lancelot: From Wikipedia, the free encyclopedia. Below is a table of the comparison and contrast of the transistors, with an explanation of ddatasheet everything in the table means below it. An MJ PNPwhich is also manufactured using the epitaxial process today, is a complementary transistor to the 2N This means the 2N will suffice perfectly fine for these applications. However, it doesn’t necessarily mean it’s the transistor that you should use. This means they are both controlled by current applied to the base and provide current amplification at the collector-emitter end.

Retrieved 7 November Transistor Man looks at the current going from the base to the emitter. How they differ is that the 2N can handle greater operating collector current. Commons category link is on Wikidata.


It was produced exclusively by the Czechoslovakian electronics company Tesla. It was introduced in the early s by RCA using a hometaxial transistoe transistor process, transitioned to an epitaxial base in the mids. The 2N is a common NPN bipolar junction transistor used for general-purpose low-power amplifying or switching applications. This page was last edited transustor 18 Octoberat This page was last edited on 22 Novemberat Also the higher frequency response has improved performance when used in audio amplifiers.

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

So if you need to transitor an amplifier with a gain ofyou set up 3 transistor stages. A good rule of thumb is to build it using the minimum beta value instead of the max:.

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. KD is a higher power equivalent used in Eastern Bloc countries, and is intended for general purpose applications.

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.

Modern 2N datasheets often, but not always, specify f T of 2. It has a transition frequency of 2. Circuitbuilding do-it-yourself for Dummies.

These really are extreme conditions. From Wikipedia, the free encyclopedia.
