In datashest you’re curious about which to use, or which one is better or superior than 2n309 other, in this article, we compare and contrast the 2 transistors. Archived from the original on Below is a table of the comparison and contrast of the transistors, with an explanation of what everything in the table means below it.

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power version of the 2N, rated at 25 W55 V and 4 Abut became almost obsolete about the late s when many TO devices were withdrawn from mainstream manufacturers’s lists.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 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. From Wikipedia, the free encyclopedia. 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: So in this way, the 2N does have superiority in that it can handle greater current.

In these ways, the 2N and the 2N are both identical.

The 2N and the 2N are 2 of the most popular NPN bipolar junction transistors in the electronics market. Variants with higher voltage ratings e.

The 2N remains very popular as a series pass transistor in linear power supplies and is still used in for medium- current and high- power circuits generally, including low frequency power converters although its use in audio power amplifiers and DC-to-AC inverters is now less common and its use in higher frequency switch-mode applications never was very practical.

Filed under beta hfe gain 2n tymkrs amplification transistor man transistors. The frequency at which gain begins to drop off may be much lower, see below. Other manufacturers around this time also would specify similar values 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.

However, when you are dealing with electronics, unless you are in power electronics, you will pretty much never need amperage this high.

An MJ PNPwhich is also manufactured using the epitaxial process today, is a complementary transistor to the 2N When figuring out DC current gain, the beta value is part of the formula. Modern successors to the 2N can datsaheet much more suitable in fast-switching circuits or high-end audio power amplifiers. These all normally require much less than mA to be powered on. This page was last edited on 18 Octoberat This means they are both controlled by current applied to the base and provide current amplification at the collector-emitter end.

In other projects Wikimedia Commons. This page was last edited on 22 Novemberat Sometimes the V CBO breakdown voltage the maximum voltage between collector and base, with the emitter open, an unrealistic arrangement in practical circuits is given as the only voltage rating, which can cause confusion.

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 Nevertheless, a 2N and many other power transistors originating from this era cannot trnsistor 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.


With an “infinite” heatsink, that is: In the sheet above, it is also known as as hFE.

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 transisor love smashing a whole bunch of letters and numbers together to make chip names sound ridiculous. 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.

If you need greater than mA but less than 1A, then the 2N will be the fatasheet to use.

The art of electronics 2nd ed. It was introduced in the early s by RCA using a hometaxial power transistor process, transitioned to an epitaxial base in the mids. The complementary PNP transistor is 2N A 2N can handle up to 5 times that amount, since it can handle up to 1A ampere of current flow from the emitter to collector to power on a load. Also the higher frequency response has improved performance when used in audio amplifiers.
