2N3955 MOSFET. Datasheet pdf. Equivalent
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 team of design, production, and applications engineers received RCA Electronic Components achievement awards in Modern 2N datasheets often, but not always, specify f T of 2. 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.
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. Retrieved 7 November The 2Nwith a TO-3 case has slightly lower gain but significantly higher maximum ratings W, Vceo, 16 Amps.

The device is designed to operate with an efficient heatsink, but care must be taken to mount the device properly,    else adtasheet damage or worsened power handling may result, especially with cases or heatsinks that are not perfectly flat.
Variants with higher voltage ratings e. 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.
KD are packaged in datqsheet TO-3 case style called T41 by Teslait is a 20 amp80 voltwatt power transistor. The frequency at which gain begins to drop off may be much lower, see below. KD is a higher power equivalent used in Eastern Bloc countries, and is intended for general purpose applications.
From Wikipedia, the free encyclopedia. Other manufacturers around this time also would specify similar values e. Modern successors to the 2N can be much more suitable in fast-switching circuits or high-end audio power amplifiers.
Wikimedia Commons has media related to 2N 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 2n33955 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 was produced exclusively by the Czechoslovakian electronics company Tesla.
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. Views Read Edit View history. Build your own low-power transmitters: 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.
Although the original 2N went into datahseet relative to epitaxial-base transistors because of high manufacturing costs, datazheet epitaxial-base version continued to be used in both linear amplifiers and switching supplies.
The art of electronics 2nd ed. This page was last edited on 22 Novemberat Retrieved 31 October 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.
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 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. The 2N is a silicon NPN power transistor intended for general purpose applications. The KD have higher power and higher current than 2N 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.
With an “infinite” heatsink, that is: It was second sourced by other manufacturers; Texas Instruments listed a single-diffused mesa version of the device in an August datasheet.
