They are also identical in the amount of voltage they can handle aross the collector-to-emitter terminals- both can handle up to 40V. Variants with higher voltage ratings e.

2N3904 Datasheet, Equivalent, Cross Reference Search

Now hFE and beta cannot be greater in value than allowed by the gain. Nevertheless, a 2N and many other power transistors originating from this era cannot be 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 changes to semiconductor manufacturing technology, the original process became economically uncompetitive in the mids, and a similar device was created using epitaxial base technology.

Datashret 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. This transistor is low-cost, widely available and sufficiently robust to be of use by experimenters and electronics hobbyists.

KD is a higher power equivalent used in Eastern Bloc countries, and is intended for general purpose applications. The 2Nwith a TO-3 case has slightly lower gain but significantly higher daatasheet ratings W, Vceo, 16 Amps. These all normally require much less than mA to be powered on. The art of electronics 2nd ed. In other projects Wikimedia Commons. So in this way, the 2N does have superiority in that it can handle greater 2n30944.

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.

2N3904 vs 2N2222

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. It is used in a variety of analog amplification and switching applications.

It has a transition frequency of 2. How they differ is that the 2N can handle greater operating collector current. This page was last edited on 22 Novemberat The robot builder’s bonanza 2nd ed. Comparing transistors isn’t extensive, as there are only a few very useful parameters that matter. 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.

Filed under beta hfe gain 2n tymkrs amplification transistor man transistors. Anyway so somehow they got to explaining how to find the DC current gain of a transistor based on its datasheet and such:. This means they are both controlled by current applied to the base and provide tdansistor amplification at the collector-emitter end. In simplicity, this really means that 40V is the maximum amount of voltage that the transistor can tolerate minus transisyor voltage drop across the load connected to the collector.

Retrieved 7 November The 2N remains very popular as a series pass transistor in linear power supplies and is still used in for traansistor 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.

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. Below is a table of the comparison and contrast of the transistors, with an datasbeet of what everything in the table means below it.

The 2N and the 2N are 2 of the most popular NPN bipolar junction transistors in the electronics market. So if you need to build an amplifier with a gain ofyou set up 3 transistor stages.

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

KD 23094 packaged in a TO-3 case style called T41 by Teslait is a 20 amp80 voltwatt power transistor. And if you need greater current, the TIP can handle up to 15A. 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 With an “infinite” heatsink, that is: 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.

Traansistor from the original on It was produced 23n094 by the Czechoslovakian electronics company Tesla. 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. These really are extreme conditions. And if you need greater than 1A at the output, then a darlington transistor such as the TIP transistor can be used, which can handle up to 5A of amplified current.
