2N3955 MOSFET. Datasheet pdf. Equivalent
Retrieved 7 November It was second sourced by other manufacturers; Texas Instruments listed a single-diffused mesa version of the device in an August datasheet. Commons category link from Wikidata. Graf; William Sheets RCA by had changed their specification to give 2.
Retrieved 31 October Wikimedia Commons has media related to 2N 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. Ddatasheet 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 The 2N is a silicon NPN power transistor intended for general purpose applications.
An N23955 PNPwhich is also manufactured using the epitaxial process today, is a complementary transistor to the 2N 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 robot builder’s bonanza 2nd ed.
Variants with higher voltage ratings e. The KD have higher power and higher current than 2N With an “infinite” heatsink, that is: The team of design, production, and applications engineers received RCA Electronic Components achievement awards in 2n39555 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 one dollar, and became an industry workhorse standard.
The device is designed to operate with an efficient heatsink, but care must be taken to mount the device dxtasheet,    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 art of electronics 2nd ed. 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. Build your own low-power transmitters: This page was last edited on 22 Novemberat The 2N is a much lower power version of the satasheet, rated at 25 W55 V and 4 Abut became almost obsolete about the late s when many TO devices were withdrawn from mainstream manufacturers’s lists.
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.
It was introduced in the early s by RCA using a hometaxial power transistor process, transitioned to an epitaxial base in the mids. 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. In other projects Wikimedia Commons.

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. Modern successors to the 2N can be much more suitable in fast-switching circuits or high-end audio power amplifiers. Modern 2N datasheets datadheet, but not always, specify f T of 2. Also the higher frequency response has improved performance when used in audio amplifiers.
