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.
Nevertheless, a 2N and many other power transistors originating from this era cannot be assumed to have great high-frequency performance datasheey there can be degradation of phase-shift and open-loop gain even within the datashset frequency range.

This page was last edited on 22 Novemberat The device is designed to 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. Views Read Edit View history. 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.
Graf; William Sheets Retrieved 7 November 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.
2N UTC PNP A Vceo
2nn2955 It was introduced in the early s by RCA using a hometaxial power transistor process, transitioned to an epitaxial base in the mids.
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. The art of electronics 2nd ed. An MJ PNPwhich is also manufactured using the epitaxial process today, is datashewt complementary transistor to the 2N 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.
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power version of the 2N, rated at 25 W55 V and 4 Abut became almost obsolete about the late s when many TO devices were withdrawn from mainstream manufacturers’s lists. Other manufacturers around this time also would specify similar values e. KD is a higher power equivalent used in Eastern Bloc countries, and is intended for general purpose applications.
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, dztasheet can cause confusion. 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.
The KD have higher power and higher current than 2N It has a transition frequency of 2.
It was produced exclusively by the Czechoslovakian electronics company Tesla. Build your own low-power transmitters: The 2N is a silicon NPN power transistor intended for general purpose datasheeh. The frequency at which gain begins to drop off may be much lower, see below.

Wikimedia Commons has media related to 2N Retrieved from ” https: 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. KD are packaged in a TO-3 case style called T41 by Teslait is a 20 amp80 voltwatt power transistor. The robot builder’s bonanza 2nd ed. From Wikipedia, the free encyclopedia.
It was second sourced by other manufacturers; Texas Instruments listed a single-diffused mesa version of the device in an August datasheet.
Variants with higher voltage ratings e. RCA by had changed their specification to give 2. Modern successors to the 2N can be much dataeheet suitable in fast-switching circuits or high-end audio power amplifiers. With an “infinite” heatsink, that is:
