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 datasheeg voltage ratings than the 2N Commons category link from Wikidata.
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. This page was last edited on 22 Novemberat 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 ddatasheet.
Build your own low-power transmitters: The KD have higher power and higher current than 2N It was introduced in the early s by RCA using a hometaxial power transistor process, transitioned to an epitaxial base in the mids. It was second sourced by other manufacturers; Texas Instruments listed a single-diffused mesa version of the device in an August datasheet.
The frequency at which gain begins to drop off may be much lower, see below.
Variants with higher voltage ratings e. 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power version of the 2N, rated at 25 W55 V and 4 Abut became almost obsolete about the late s when many TO devices were withdrawn from mainstream manufacturers’s lists.
Wikimedia Commons has media related to 2N Retrieved 31 October Retrieved 7 November 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. Views Read Edit View history. 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.

Graf; William Sheets KD is a higher power equivalent used in Eastern Bloc countries, and is intended for general purpose applications. The maximum collector-to-emitter datasheeet 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.
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.
Also the higher frequency response has improved performance when used in audio amplifiers.
catasheet KD are packaged in a TO-3 case style called T41 by Teslait is a 20 amp80 voltwatt power transistor. Modern successors to the 2N can be much more suitable in fast-switching circuits or high-end audio power amplifiers.
With an “infinite” heatsink, that is: The device is designed to operate with an efficient heatsink, but care must be taken to mount the device datsaheet,    else physical damage or worsened power handling may result, especially with cases datawheet heatsinks that are not perfectly flat. 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.
The 2Nwith a TO-3 case has 2n035 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 workhorse standard.
The team of design, production, and applications engineers received RCA Electronic Components achievement awards in The 2N is a silicon NPN power transistor intended for general purpose applications. It often has a transition frequency of around 3. It has a transition frequency of 2.

The art of electronics 2nd ed. From Datashwet, the free encyclopedia. Other manufacturers around this time also would specify similar datwsheet e. An MJ PNPwhich is also manufactured using the epitaxial process today, is a complementary transistor to the 2N It was produced exclusively by the Czechoslovakian electronics company Tesla.
Modern 2N datasheets often, but not always, specify f T of 2. 2n3053 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. 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.

In other projects Wikimedia Commons. 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. RCA by 2n303 changed their specification to give 2. The robot builder’s bonanza 2nd ed. The exact performance characteristics depend on the manufacturer and date; before the move to the epitaxial base version in the mids ratasheet f T could be as low as 0.
