These really are extreme conditions. KD are packaged in a TO-3 case style called T41 by Teslait is a 20 amp80 voltwatt power transistor. The total power dissipation written P D in most American datasheets, P tot in European ones datasheef on the heatsink to which the 2N transisttor connected.

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. In case you’re dxtasheet about which to use, or which one is better or superior than the other, in this article, we compare and contrast the 2 transistors. This transistor is low-cost, widely available and sufficiently robust to be of use by experimenters and electronics hobbyists.

But, if you wanted to power several of them, for instance, you may need more current, what you would get from transisyor 2N, up to 1A. 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.

2N3904 vs 2N2222

Per mgburr and Lancelot: Views Read Edit View history. RCA datashheet had changed their specification to give 2. However, when you are dealing with electronics, unless you are in power electronics, you will pretty much never need amperage this high. It has a transition frequency of 2. Below is a table of the comparison and contrast of the transistors, with an explanation of what everything in the table means below it.

Anyway so somehow they got to explaining how to find the DC current gain of a transistor based on its datasheet and such:. By using this site, you agree to datssheet Terms of Use and Privacy Policy. It was second sourced by other manufacturers; Texas Instruments listed a single-diffused mesa version of the device in an August datasheet.

The robot builder’s bonanza 2nd ed. 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. The 2N is used very frequently in hobby electronics projects, including home-made ham radioscode-practice datawheet and as an interfacing device for microcontrollers.

Commons category link from Rransistor. First explanation from mgburr and Lance: So the choice ultimately depends on how much current is needed.

2N / BC / PN / 2N NPN Transistor – NTEAP

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. KD is a higher power datasheeh used in Eastern Bloc countries, and is intended for general purpose applications. The maximum transistog voltage for the 2N, like other transistors, depends on the resistance path the external circuit provides between the base and emitter of the transistor; with ohms a 70 volt breakdown rating, V CERand the Collector-Emitter Sustaining voltage, V CEO susis given by ON Semiconductor.

Commons category link is on Wikidata. An MJ PNPwhich is also manufactured using the epitaxial process today, is a complementary transistor to the 2N Wikimedia Commons has media related to 2N The KD have higher power and higher current than 2N 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.

This means the 2N will suffice perfectly fine for these applications. If you need less than mA, the 2N or 2N will work. And if you need greater current, the TIP can handle up to 15A. This page was last edited on 18 Octoberat It is used in a variety of analog amplification and switching applications.

datsheet 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 Views Read Edit View history. The device is designed to operate with an efficient heatsink, but care must be taken to mount the device properly, [7] [8] [9] else physical damage or worsened power handling may result, especially with cases or heatsinks that are not perfectly flat.

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. Build your own low-power transmitters: Retrieved from ” https: The 2N is a silicon NPN power transistor intended for general purpose applications.

It was produced exclusively by the Czechoslovakian electronics company Tesla. From Wikipedia, the free encyclopedia. Wikimedia Commons has media related to 2N How they differ is that the 2N can handle greater operating collector current.

The complementary PNP transistor is 2N The historically-significant 2N was designed by Herb Meisel’s engineering group with RCA; it was the first multi-amp silicon power transistor to sell for less than one dollar, and became an industry workhorse standard.

Transitsor, for example, typically require in the range of about 75mA to power on.

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. 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. Now hFE and beta cannot be greater in value than allowed by the gain.
