The general specifications of the various variants are similar, with the biggest difference being the maximum allowable current and power dissipation.

Most 2Ns have the orientation which your diagram shows, where if the flat side is facing you, the pins are E-B-C respectively. Archived from the original on 14 April The maximum amount of current that could flow through the Collector pin is mA, hence we cannot connect loads that consume more than mA using this transistor.

I have used a base voltage of 5V and a value of 1K as current limiting resistor. They’re listed together because they’re complementary transistors.

In actual circuit modifications might be required. From Wikipedia, the free encyclopedia.

2NA Pinout, Features, Equivalent & Datasheet

I am trying to figure out what is going on here. Wikimedia Commons has media related to 2N Home Questions Tags Users Unanswered.


So if you looking for an NPN transistor that could switch loads of higher current then 2NA might the right choice for your project. Typical examples are the well known NPN and PNP industrial and military types, 2N and 2N, which have dwtasheet used for over four decades and are still being used in many designs. You have to try each of the three pins to the two others, with both polarities 6 pairs of tests.

Other part numbers will have different parameters. Javier Loureiro 1 7 Zuofu 3, 2 15 To confirm, you can dstasheet check with the hFE function if your meter has that.

The 2N is considered a very common transistor, [1] [2] [3] and is used as an exemplar of an NPN transistor. Note that the motor datasheet 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. Junkbots, bugbots, and bots on wheels: This transistor will make it forward biased and thus closes the connection between collector and emitter.

It can be even worse, since the On Semi PN has the conventional pinout, despite being the same manufacturer and mostly same specifications: When I apply a voltage between the pin 1 to 3, as soon as the voltage rises over about 8V, the current starts to flow, even when the base has no voltage pulled down or floatingand the transistors gets pretty hot. Billions of units have been manufactured over datashert past 45 years and there is continuing high volume annual production.


Therefore, it is important to refer to the datasheet for the exact part number and manufacturer. Absolute maximum rating for emitter-base voltage is 6V hence the E-B junction broke down and started conducting.

Am I missing something here?

How to use 2NA This transistor like all can be used either as a switch or as an amplifier. Retrieved 26 March But there are two important features that distinguish both. All variations have a beta or current gain h fe of at least in optimal conditions.

Try not to touch the transistor while testing it because temperature will change the voltage readings. Learn to keep an eye open for the following transistors, as n2222a among the most useful, inexpensive, and popular types: When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter.
