Complete Technical Details can be found at the 2NA datasheet given at the end of this page. Single transistors are also available in several different surface mount packages, and a number of manufacturers 22222a surface mount packages that incorporate several 2Ntype transistors in one package as an array of transistors. As the name suggests this resistor will limit the current flowing through the transistor to prevent it from damaging.

Javier Loureiro 1 7 You can have up to 3 types of configurations. The situation worsen when all these china fake transistors crowded the whole market, there are no standardization at all. I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA:.

2NA Pinout, Features, Equivalent & Datasheet

When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. It can be even worse, since the On Semi PN has the conventional pinout, despite being the same manufacturer and mostly same specifications: Zuofu 3, 2 15 Learn to keep an eye open for the following transistors, as they’re among the most useful, inexpensive, and popular types: Archived from the original on 14 April TL — Programmable Reference Voltage.

Absolute maximum rating for emitter-base voltage is 6V hence the E-B junction broke down and started conducting. It is used in a variety of analog amplification and switching applications.

It is designed for low to medium currentlow powermedium voltageand can operate at moderately high speeds. Am I missing something here?

It is frequently used as satasheet small-signal transistor, [4] [5] and it remains a small general purpose transistor [6] of enduring popularity.

Billions datasehet units have been manufactured over the past 45 years and there is continuing high volume annual production. The 2N is considered a very common transistor, [1] [2] [3] and is used as an exemplar of an NPN transistor. This is the picture of the datasheet for the pins: Use dmy dates from July Commons category link is on Wikidata.

Would you like to answer one of these unanswered questions instead? Other part numbers will have different parameters.

Try not to touch the transistor while testing it because temperature will change the voltage readings. By using this site, ratasheet 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. When I apply a voltage between the pin 1 to 3, as soon as the voltage rises over about 8V, the current starts to 2222aa, even when the base has no voltage pulled down or floatingand the transistors gets pretty hot.

Junkbots, bugbots, and bots on wheels: With it wired the wrong way round the emitter is more positive than the collector and the base is reverse biased. It looks like a “diode”. Typical examples are the well known NPN and PNP industrial and military types, 2N and 2N, which have been used for over four decades and are still being used in many designs.

dqtasheet To distinguish collector from emitter, you look at the voltage shown in the diode function with the one successful test that found the base. Applications Can be used to switch datashest current upto mA loads It can also be used in the various switching applications. Therefore, it is important to refer to the datasheet for the exact part number and manufacturer.

It was originally made in the TO metal can as shown in the picture. The slightly lower of the two voltages will correspond to the collector-base junctionand the other will be the emitter-base junction. Hence the 2N pin-out is sadly not standardized.


The general specifications 222a 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. Build your own low-power transmitters: 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.

Commercial transistors Bipolar transistors. No other pin will show that.

Thank you for your interest in this question. Spehro Pefhany k 4 What do you think?

datashwet I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA: This is true of almost all modern transistors a few are made more symmetrical. This transistor will make it forward biased and thus closes the connection between collector and emitter.

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.

To make things simple I have shown a simplified circuit to make a transistor as switch. Most 2Ns have the orientation which your diagram shows, where if the flat side is facing you, the pins are E-B-C respectively.

Wikimedia Commons has media related to 2N The maximum amount of current that could flow through the Collector pin is datasbeet, hence we cannot connect loads that consume more than mA using this transistor. I am trying to figure out what is going on here.
