So the choice ultimately depends on how much current is needed. The 2N is a common NPN bipolar junction transistor used for general-purpose low-power amplifying or switching applications. 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.
Typical components that may require a transistor in order to be driven are motors, buzzers, solenoids, and high-power LEDs. Wikimedia Commons has media related to 2N Circuitbuilding do-it-yourself for Transisyor. The 2N is used very frequently in hobby electronics projects, including home-made ham radioscode-practice oscillators and as an interfacing device for microcontrollers.

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. If you need less than mA, the 2N or 2N will work. It was second sourced by other manufacturers; Texas Instruments listed a single-diffused mesa version of the device in an August datasheet.
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. Commons category link is on Wikidata.
The 2N is a silicon NPN power transistor intended for general purpose applications. 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. Anyway so somehow they got to explaining how to find the DC current gain of a transistor based on its datasheet and such:.
When figuring out DC current gain, the beta value is part of the formula. If you need greater tansistor mA but less than 1A, then the 2N will be the one to use.
Build your own low-power transmitters: Motors, for example, typically require in the range of about 75mA to power on. With changes to semiconductor manufacturing technology, the original process became economically uncompetitive in the mids, and a similar device was created using epitaxial base technology.

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 voltage that the transistor can tolerate minus the voltage drop across the load connected to the collector.
Graf; William Sheets This page was last edited on 22 Novemberat Now hFE and beta cannot be greater in value than allowed by the gain. Comparing transistors isn’t extensive, as there are only a few very useful parameters that matter. Filed under beta hfe gain 2n tymkrs amplification transistor man transistors.
This wouldn’t be acceptable, transixtor it exceeds the maximum V CEO.
Modern successors to the 2N can be much more suitable in fast-switching circuits or high-end audio power amplifiers. Per mgburr and Lancelot: It has a transition frequency of 2. This page was last edited on 18 Daasheetat KD is a higher power equivalent used in Eastern Bloc countries, and is intended for general purpose applications.
RCA by had changed their specification to give 2.
Beta? Hfe? Gain? 2Ns! I think its transistor
So in this way, the 2N does have superiority in that it can handle greater current. These really are extreme conditions. Retrieved from ” https:
