The 2N is a silicon NPN power transistor intended for general purpose applications. And if you need greater current, the TIP can handle up to 15A. Per mgburr and Lancelot: A good rule of thumb is to build it using the minimum beta value instead of the max:. It has a transition frequency of 2. Variants with higher voltage ratings e. 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.
KD is a higher power equivalent used in Eastern Bloc countries, and is intended for general purpose applications. 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.
Anyway so somehow they trransistor to explaining how to find the DC current gain of a transistor based on its datasheet and such:. 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.
How they differ is that the 2N can handle greater operating collector current. Modern successors to the 2N xatasheet be much more suitable in fast-switching circuits or high-end audio power amplifiers.
This page was last edited on 22 Novemberat The 2N is a common NPN bipolar junction transistor used for general-purpose low-power amplifying or switching applications. Wikimedia Commons has media related to 2N It is designed for low current and powermedium voltageand can operate at moderately high speeds. Retrieved 7 November It was introduced in the early s by RCA using a hometaxial power transistor process, transitioned to an epitaxial base in the mids.
The 2N is used very transisttor in hobby electronics projects, including home-made ham radioscode-practice oscillators and as an interfacing device for microcontrollers. 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. 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.
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. In other projects Wikimedia Commons. So if you need to build daatsheet amplifier with a gain ofyou set up 3 transistor stages.
In the sheet above, it is also known as as hFE. TOP Related Posts.
