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 Retrieved from ” https: The device is designed ke503 operate with an efficient heatsink, but care must be taken to mount the device properly,    else physical damage or worsened power handling may result, especially with cases or heatsinks that are not perfectly flat.
Home Questions Tags Users Unanswered. Modern 2N datasheets often, but not always, specify f T of datasneet. Email Required, but never shown.
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.
It was dahasheet in the early s by RCA using a hometaxial power transistor process, transitioned to an epitaxial base in the mids. Other manufacturers around this time also would specify similar values e.
The robot builder’s bonanza 2nd ed. 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.
John M 94 8. 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 Also the higher frequency response has improved performance when used in audio amplifiers.
Philips ON Ask Question. Having reverse-engineered the circuit, I’m fairly certain that it’s a NPN transistor, but I’ve found some references mentioning a Darlington transistor was used on the ECU. With an “infinite” heatsink, that is: KD are packaged in a TO-3 case style called T41 by Teslait is a 20 amp80 voltwatt power transistor. Commons category link from Wikidata. Graf; William Sheets KD is a higher power equivalent used in Eastern Bloc countries, and is intended for general purpose applications.
The 2Nwith a TO-3 case has slightly lower gain but significantly higher maximum ratings W, Vceo, 16 Amps. Variants with higher voltage ratings e. It has a transition frequency of 2. Views Read Edit View history. The frequency at which gain begins to drop off may be much lower, see below.
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. An MJ PNPwhich is also manufactured using the epitaxial process today, is a complementary transistor to the 2N 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 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. Retrieved 31 October It datawheet produced exclusively by the Czechoslovakian electronics company Tesla.

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. It often fatasheet a transition frequency of around 3.
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.
RCA by had changed their specification to give 2. In other projects Wikimedia Commons. 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 experimenters.
