Build your own low-power transmitters: 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 Datazheet susis given by ON Semiconductor.

In other datasneet Wikimedia Commons. 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.

KD is a higher power equivalent used in Eastern Bloc countries, and is intended for general purpose applications. Retrieved 31 October This page was last edited on 22 Novemberat With an “infinite” heatsink, that is: The exact performance characteristics depend on the manufacturer and date; before the move to the 2j3054 base version in the mids the f T could be as low as 0.

An MJ PNPwhich is also manufactured using the epitaxial process today, is a complementary transistor to the 2N The 2N is a much lower power version of the 2N, rated datasheeh 25 W55 V and dataheet Abut became almost obsolete about the late s when many TO devices were withdrawn from mainstream manufacturers’s lists.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 It was introduced in the early s by RCA using a hometaxial power transistor process, transitioned to an epitaxial base in the mids.


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. The frequency at which gain begins to drop off may be much lower, see below.

Variants with higher voltage ratings e.

It was second sourced by other manufacturers; Texas Instruments listed a single-diffused mesa version of the device in an August datasheet. 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.

Modern successors to the 2N can be much more suitable in fast-switching circuits or high-end audio power amplifiers. The 2N is a silicon NPN power transistor intended for general purpose applications. datasjeet

The 2N remains very popular as a series pass dxtasheet in linear power supplies and is still used in for medium- current datashet 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 has a transition frequency of 2. The team of design, production, and applications engineers received RCA Electronic Components achievement awards in 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.


Retrieved 7 November Other manufacturers around this time also would specify similar values e. Commons category link from Wikidata. Also the higher frequency response has improved performance when used in audio amplifiers.

Retrieved from ” https: It often has a transition frequency of around 3. The robot builder’s bonanza 2nd ed. The 2Nwith a TO-3 case has slightly lower gain but significantly higher maximum ratings W, Vceo, 16 Amps. KD are packaged in a Datasheett case style called T41 by Teslait is a 20 amp80 voltwatt power transistor.

Although the original 2N went into decline relative to epitaxial-base transistors because daatsheet high manufacturing costs, the epitaxial-base version continued to be used in both linear amplifiers and switching supplies.

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. The KD have higher power and higher current than 2N Sometimes the V CBO breakdown voltage the maximum voltage between collector and base, with the 23054 open, an unrealistic arrangement in practical circuits is given as the only voltage rating, which can cause confusion.

RCA by had changed their specification to give 2. The art of electronics 2nd ed. Graf; William Sheets Views Read Edit View history. From Wikipedia, xatasheet free encyclopedia.
