The 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 datashet workhorse standard.

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.

Variants with higher voltage ratings e. Graf; William Sheets An MJ PNPwhich is also manufactured using the eatasheet process today, is a complementary transistor to the 2N 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 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 was second sourced by other manufacturers; Texas Instruments listed a single-diffused mesa version of datasheft device in an August datasheet.


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 datashret audio frequency range.

Datashheet Commons has media related to 2N Retrieved 31 October 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.

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 Retrieved 7 November From Wikipedia, the free encyclopedia. Datadheet 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.

datazheet The 2Nwith a TO-3 case has slightly lower gain but significantly higher maximum ratings W, Vceo, 16 Amps. 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 dattasheet 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 2n335 has a transition frequency of around 3. 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. It was produced exclusively by the Czechoslovakian electronics company Tesla.

The KD have higher power and higher current than 2N Also the higher frequency response has improved performance when used in audio amplifiers.

Modern successors to the 2N can be much more suitable in fast-switching circuits datahseet high-end audio power amplifiers. Modern 2N datasheets often, but not 2n30035, specify f T of 2. 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 datqsheet 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.
