Would you like to answer one of these unanswered questions instead? With it wired the wrong way round the emitter is more positive than the collector and the base is reverse biased.

Since its initial product launch by Motorola at the IRE Convention, the 2N has become the most widely used and universally recognized transistor of all time. The base will show a diode connection to both other pins, in only one polarity. The general specifications of the various variants are similar, with the biggest difference being the maximum allowable current and power dissipation.

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.

No other pin will show that. Junkbots, bugbots, and bots on wheels: Note that the motor here draws about mA from the 12V power source, since the 2N has collector current rating upto mA this circuit is possible had it been a BC the transistor should have been burnt. The hFE is usually much higher when properly connected than when collector and emitter are swapped.


The JEDEC registration of a device number ensures particular rated values will be met by all parts offered under that number. By using this site, you agree to the Terms of Use and Privacy Policy.

How to use 2NA This transistor like all can be used either as a switch or as an amplifier. It is used in a variety of analog amplification and switching applications. From Wikipedia, the free encyclopedia.

Other part numbers will have different parameters. What do you think? Thank you for your interest in datashee question. Retrieved from ” https: Applications Can be used to switch high current upto mA loads It can also be used in the various switching applications.

Submitted by webmaster on 11 December The situation worsen when all these china fake transistors crowded the whole market, there are no standardization at all. You have to try each of the three datwsheet to the two others, with both polarities 6 pairs of tests.

2NA Pinout, Features, Equivalent & Datasheet

Datashee Loureiro 1 7 I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA: High frequency and microwave engineering. The 2N exhibits its forward gain beta peak at a lower current than the 2N, and is useful in amplifier applications with reduced I ce. But there are two important features that distinguish both. Would I reuse it?

Home Questions Tags Users Unanswered. Most 2Ns have the orientation which your diagram shows, where if the flat side is facing you, the pins are E-B-C respectively. The 2N is considered a very common transistor, [1] [2] [3] and is used as an exemplar of an NPN transistor. Use dmy dates from July Commons category link is on Wikidata. I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA:. So if you looking for an NPN transistor that could switch loads of higher current then 2NA might the right choice for your project.


Wikimedia Commons has media related to 2N They’re listed together because they’re complementary transistors. Commercial transistors Bipolar transistors. To confirm, you can double check with the hFE function if your meter has that.

JEDEC registered parameters include outline dimensions, small-signal current gaintransition frequencymaximum values for voltage withstand, current rating, power dissipation and temperature rating, and others, measured under standard test conditions.

The BC is a low voltage, low current, general-purpose switching transistor in a TO package. To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA. In other projects Wikimedia Commons.

The Base-Emitter voltage of this transistor is 6V so you just have to supply this voltage across the base and emitter of the transistor to induce a base current into the transistor. As the name suggests this resistor will limit the current flowing through the transistor to prevent it from damaging.
