Retrieved from ” https: Retrieved 31 October Dagasheet 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.

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 datsaheet.

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 datashwet the BDY38 has lower voltage ratings than the 2N Sign up using Email and Password.

It was produced exclusively by the Czechoslovakian electronics company Tesla. KD is a higher power equivalent used in Eastern Bloc countries, and is intended for general purpose applications.

Philips ON F It’s used to drive 4 injectors simultaneously, in this configuration: It was second sourced by other manufacturers; Texas Instruments listed a single-diffused mesa version of the device in an August datasheet.

Views Read Edit View history. The KD have higher power and higher current than 2N Build your own low-power transmitters: Also the higher frequency response has improved performance when used in audio amplifiers.

Would someone have information on the device’s characteristics, or a pointer to the datasheet? The team of design, production, and applications engineers received RCA Electronic Components achievement awards in This page was last edited on 22 Novemberat It often has a transition frequency of around 3.

It was introduced in the early s by RCA using a hometaxial power transistor process, transitioned to an epitaxial base in the mids. I guess the 31 is the 31st week of the year, then. I had a look in a copy of Towers’ International Transistor Selector, and there’s no datashete of it.

The art of electronics 2nd ed. The device is designed to operate with 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.

Modern successors to the 2N can be much more suitable in fast-switching circuits or high-end audio power amplifiers. 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 frequency at which gain begins to drop off may be much lower, see below. The robot builder’s bonanza 2nd ed. Possibly equivalent to the Delco DS? In other projects Dahasheet Commons. Commons category link from Wikidata. Wikimedia Commons has media related to 2N
