Grogrel The art of electronics 2nd ed. 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 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. An MJ PNPwhich is also manufactured using the epitaxial process today, is a complementary transistor to the 2N 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 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. 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 was second sourced by other manufacturers; Texas Instruments listed a single-diffused mesa version of the device in an August datasheet.

This page was last edited on 22 Novemberat It has a dataaheet frequency of 2. Variants with higher voltage ratings e. 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.

CITB GE PDF 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. Modern 2N datasheets often, but not always, specify f T of 2. By using this site, you agree to the Terms of Use and Privacy Policy.

The frequency at which gain begins to drop off may be much lower, see below. Graf; William Sheets It was introduced in the early s by RCA using a dwtasheet power transistor process, transitioned to an epitaxial base in the mids. Build your own low-power transmitters: Wikimedia Commons has media related to 2N Also the higher frequency datashset has improved performance when used in audio amplifiers. KD is a higher power equivalent used in Eastern Bloc countries, and is intended for general purpose applications.

Retrieved 7 November 2n Modern successors to the 2N can be much more suitable in fast-switching circuits or high-end audio power amplifiers. 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 KD have higher power and higher current than 2N 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.

From Wikipedia, the free encyclopedia. Datasheeet other projects Wikimedia Commons. Other manufacturers around this time also would specify similar values e. It often has a transition frequency of around datsheet. PDF 2N Datasheet download 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 dxtasheet switch-mode applications never was very practical.

Views Read Edit View history. 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 team of design, production, and applications engineers received RCA Electronic Components achievement awards in The 2Nwith a TO-3 case has slightly lower gain but significantly higher maximum ratings W, Vceo, 16 Amps.
