It is designed for low current and powermedium voltageand can operate at moderately high speeds. Wikimedia Commons has media related to 2N This wouldn’t be acceptable, since it exceeds the maximum V CEO. Retrieved 7 November In other projects Wikimedia Commons. RCA by had changed their specification to give 2. Retrieved 31 October Retrieved from ” https: Views Read Edit View history.

The art of electronics 2nd ed. With an “infinite” heatsink, that is: 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.

This means that in a circuit, voltage and current are biased to them the same exact way- they both must receive positive voltage to the base and collector terminals in order to operate.

Usually a 2N will suffice for most circuits, but if you need more than mA, then you should use a 2N instead. Commons category link is on Wikidata.

However, it doesn’t necessarily mean it’s the transistor that you should use. 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 2n394 them. A 2N can handle up to 5 times that amount, since it can handle up to 1A ampere of current flow from trnsistor emitter to collector to power on a load. Below is a table of the comparison and contrast of the transistors, with an explanation of what everything in the table means below it.


It was second sourced by other manufacturers; Texas Instruments listed a single-diffused mesa version of the device in an August datasheet. 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.

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 dataeheet process today, is a complementary transistor to the 2N Views Read Edit View history.

Wikimedia Commons has media related to 2N First explanation from mgburr and Lance: Modern successors to the 2N can be much more suitable in fast-switching circuits or high-end audio power amplifiers. So I asked folks what their favorite transistor was for audio applications and instead of getting 10 different kinds, a few of them agreed on the 2N spoilsports: However, when you are dealing with electronics, unless you are in power electronics, you will pretty much never need amperage this high.

It often has a transition frequency of around 3. So a bunch of the folks were talking about engineering and electronics and the like in our irc room and I datashedt to talking about how engineers love datashdet a whole bunch of letters and numbers together to make tansistor names sound ridiculous.

If you need less than mA, the 2N or 2N will work. These really are extreme conditions.

The frequency at which gain begins to drop off may be much lower, see below. These all normally require much less than mA to be powered on.

Transistor Man looks at the current going from the base to the emitter. It is used in a variety of analog amplification and switching applications. It has a transition frequency of 2. KD are packaged in a TO-3 case style called T41 by Teslait is a 20 amp80 voltwatt power transistor.

In the sheet above, it is also known as as hFE. Filed under beta hfe gain 2n tymkrs amplification transistor man transistors.

This transistor is low-cost, widely available and sufficiently robust to be of use by experimenters and electronics hobbyists. And if you need greater than 1A at the output, then a darlington transistor such as the TIP transistor can be used, which can handle up to 5A of amplified current. 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 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.

It was introduced in the 2n309 s by RCA using a hometaxial power transistor process, transitioned to an epitaxial base in the mids.

The higher-power 2N is a very similar NPN transistor that can safely switch three times as much current as the 2N This means the 2N will suffice perfectly fine for these applications.
