Build your own low-power transmitters: The device is designed to operate datxsheet 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.

It was introduced in the early s by RCA using a hometaxial power transistor process, transitioned to an epitaxial base in the mids. The 2Nwith a TO-3 case has slightly lower gain but dtasheet higher maximum ratings W, Vceo, 16 Amps. Commons category link from Wikidata.

The frequency at which gain begins to drop off may be much lower, see below. 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. This page was last edited on 22 Novemberat 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.


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. It often has a transition frequency of around 3.

KD are packaged in a TO-3 case style called T41 by Teslait is a 20 amp80 voltwatt power transistor. RCA by had changed their specification to give 2. Retrieved 31 October 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 datashedt the markings.

Retrieved from ” https: 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. Modern successors to the 2N can be much more suitable in fast-switching circuits or datwsheet audio power amplifiers. 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 datsheet dollar, and became an industry workhorse standard.

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 datazheet gain even within the audio frequency range. Wikimedia Commons has media related to 2N 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.

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 in the mids, and a similar device was created using epitaxial base technology. Modern 2N datasheets often, but not always, specify f T of 2.


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.

Variants with higher voltage ratings e. An MJ PNPwhich is also manufactured using the epitaxial process today, is a complementary transistor to the 2N Also the higher frequency datasheef has improved performance when used in audio amplifiers. 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 With an “infinite” heatsink, that is: 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.

It has a transition frequency of 2. KD is a higher power equivalent used in Eastern Bloc countries, and is intended for general purpose applications. Other manufacturers around this time also would specify similar values e.

The art of electronics 2nd ed. The 2N is a much lower power version of the 2N, rated at 25 W55 V and 4 Abut became datashert obsolete about the late s when many TO devices were withdrawn from mainstream manufacturers’s lists.

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