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 transistor; with ohms a 70 volt breakdown rating, V CERand the Collector-Emitter Sustaining voltage, V CEO susis given by ON Semiconductor.

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. The KD have higher power and higher current than 2N Other manufacturers adtasheet this time also would specify similar values e.

Retrieved 31 October The frequency at which gain begins to drop off may be much lower, see below. Commons category link from Wikidata.

It often has a transition frequency of around 3. KD is a higher power equivalent used in Eastern Bloc countries, and is intended for general purpose applications. The team of design, production, and applications engineers received RCA Electronic Components achievement awards in By using this site, you agree to the Terms of Use and Privacy Policy.

The 2N is a silicon NPN power transistor intended for general purpose applications. With changes to semiconductor manufacturing technology, the original process became economically uncompetitive datasehet the mids, and a similar device was created using epitaxial base technology. RCA by had changed their specification to give 2.

Graf; William Sheets 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. In other projects Wikimedia Commons.


Nevertheless, a 2N and many other power transistors originating from this era cannot be assumed to have great n23054 performance and there can be degradation of phase-shift 2n054 open-loop gain even within the audio frequency range. It has a transition frequency of 2. Retrieved 7 November The robot builder’s bonanza 2nd ed.

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 the sixties 2n33054 early seventies, Philips produced similar devices encapsulated in TO-3 packages under the reference BDY20 described as n23054 for “hifi” purposes and BDY38 although the BDY38 has lower voltage ratings than the 2N Build your own low-power transmitters: 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 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 was produced exclusively by the Czechoslovakian electronics company Tesla. Modern successors to the 2N can be much more suitable in fast-switching circuits or high-end audio power amplifiers. 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.

The 2Nwith a TO-3 case has slightly lower gain but significantly higher maximum ratings W, Vceo, 16 Amps. 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 datashfet standard. With an “infinite” heatsink, that is: 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.


Retrieved from ” https: An MJ PNPwhich is also manufactured using the epitaxial process today, is a complementary transistor to the 2N Also the higher frequency response has improved performance when used in audio amplifiers.

KD are packaged in a TO-3 case style called T41 by Teslait is a 20 amp80 adtasheetwatt power transistor. Wikimedia Commons has media related to 2N Modern 2N datasheets often, but not always, specify f T of 2.

It was second sourced by other manufacturers; Texas Instruments listed a single-diffused mesa version of the device in an August datasheet. It was introduced in the early s by RCA using a hometaxial power transistor process, transitioned to an epitaxial base in the mids.

Views Read Edit View history. This page was last edited on 22 Novemberat 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.

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.

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.
