Retrieved 7 November Filed under beta hfe gain 2n tymkrs amplification transistor man transistors. The 2N is a silicon NPN power transistor intended for general purpose applications. Retrieved from ” https: A 2N can handle up to mA milliamperes of current flow from the emitter to collector terminal.

trasistor When figuring out DC current gain, the beta value is part of the formula. Wikimedia Commons has media related to 2N Anyway so somehow they got to explaining how to find the DC current gain of a transistor based on its datasheet and such:.

If you need less than mA, the 2N or 2N will work. 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. With an “infinite” heatsink, that is: The total power dissipation written P D in most American datasheets, P tot in European ones depends on the heatsink to which the dafasheet is connected.

If you need greater than mA but less than 1A, then the 2N will be the one to use. Also the higher frequency response has improved performance when used in audio transisgor.

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

RCA by had changed their specification to give 2. And if you need greater current, the TIP can handle up to 15A. However, when you are dealing with electronics, unless you are in power electronics, you will pretty much never need amperage this high.


This wouldn’t be acceptable, since it exceeds the maximum V CEO. This transistor is low-cost, widely available and sufficiently robust to be of use by experimenters and electronics hobbyists.

Below is a table of the comparison and contrast of the transistors, with an explanation of what everything in the table means below it. This means the xatasheet will suffice perfectly fine for these applications. 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.

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. It is designed for low current and powermedium voltageand can operate at moderately high speeds. Build your own low-power transmitters: Sometimes the V CBO breakdown voltage the maximum voltage between collector and base, with the emitter open, an unrealistic arrangement in practical circuits transostor given as the only voltage rating, which can cause confusion.

In other projects Wikimedia Commons. The higher-power 2N is a very similar NPN transistor that can safely switch three times as much current as the 2N From Wikipedia, the free encyclopedia.

However, it doesn’t necessarily mean it’s the transistor that you should use. Typical components that may require a transistor in trandistor to be driven are motors, buzzers, solenoids, and high-power LEDs. In the sheet above, it is also known as as hFE.

The transstor and the 2N are 2 of the most popular NPN bipolar junction transistors in the electronics market. The historically-significant 2N was designed by Herb Meisel’s engineering group with RCA; it datashfet the first multi-amp silicon power transistor to sell for less than one dollar, and became an industry workhorse standard. Graf; William Sheets Commons category link is on Wikidata. In case you’re curious about which to use, or datasheft one is better or superior than the other, in this article, we compare and contrast the 2 transistors.


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 fake the markings.

This page was last edited on 22 Novemberat It was introduced in the early s by RCA using a hometaxial power transistor process, transitioned to an epitaxial base in the mids. Retrieved 31 October From Wikipedia, the free encyclopedia.

The complementary PNP transistor is 2N The 2N is a much lower power version of the 2N, rated at 25 W55 V and 4 Abut became almost obsolete about the late s when many TO devices were withdrawn from mainstream manufacturers’s lists. In the sixties and early seventies, Philips produced similar devices encapsulated in TO-3 packages 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: 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.
