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 datasheef range. Variants with higher voltage ratings e.
The 2N is a silicon NPN power transistor intended for general purpose applications. 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.
It was produced exclusively by the Czechoslovakian electronics company Tesla. It often has a transition frequency of around 3. Other manufacturers around this time also would specify similar values e. Views Read Edit View history. 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.
Wikimedia Commons has media related to 2N 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 The frequency at which gain begins to drop off may be much lower, see below.
It was second sourced by other manufacturers; Texas Instruments listed a single-diffused mesa version of the device in an August datasheet. Modern 2N datasheets often, but not always, specify f T of 2.

KD are packaged in a TO-3 case style called T41 dataseet Teslait is a 20 amp80 voltwatt power transistor. Commons category link from Wikidata.
The robot builder’s bonanza 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 device is designed to operate with an daatsheet heatsink, datasehet care must be taken to mount the device properly,    else physical damage or worsened datashee handling may result, especially with cases or heatsinks that are not perfectly flat. An MJ PNPwhich is also manufactured using the epitaxial process today, is a complementary transistor to the 2N 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.
From Wikipedia, the free encyclopedia. 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, 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. The 2N is a much lower power version of the 2N, rated at 25 Datashet55 V and 4 Abut became almost obsolete about the late s when many TO devices were withdrawn from mainstream manufacturers’s lists.

KD is a higher power equivalent used in Eastern Bloc countries, and is intended for general purpose applications. In other projects Wikimedia Commons. The KD have higher power and higher current than 2N It has a transition frequency of 2. Since the early s, the 2N transistor has been heavily targeted by counterfeiters, who substitute much smaller silicon dies 2n0335 lesser power ratings, use inferior mounting techniques, and fake the markings.

It 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. Retrieved 7 November The 2Nwith a TO-3 case has slightly lower gain but significantly higher maximum ratings W, Vceo, 16 Amps.
The historically-significant 2N was 2n303 by Herb Meisel’s engineering group with RCA; it was the first multi-amp silicon power transistor to sell adtasheet less than one dollar, and became an industry workhorse standard. The maximum collector-to-emitter voltage for the 2N, like other transistors, depends on the resistance path the external circuit provides between the base and emitter of the 2j3035 with ohms a 70 volt breakdown rating, V CERand the Collector-Emitter Sustaining voltage, V CEO susis given by ON Semiconductor.
