To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA. 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-Emitter voltage of this transistor is 6V so you dtaasheet have to supply this voltage across the base and emitter of the transistor to induce a base current into the transistor. So if you looking for an NPN transistor that could switch loads of higher current then 2NA might the right choice for your project. From Wikipedia, the free encyclopedia.

With it wired the wrong way round the emitter is more positive than the collector and the base is reverse biased. Complete Technical Details can be found at the 2NA datasheet given at the end of this page. Retrieved from ” https: This is true of almost daatasheet modern transistors ratasheet few are made more symmetrical.

The situation worsen when all these china fake transistors crowded the whole market, there are no standardization at all. The JEDEC registration of a device number ensures particular rated values will be met by all parts offered under that number. I don’t think so – throw it in the bin. They’re listed together because they’re complementary transistors. I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA:. The hFE is usually much higher when properly connected than when collector and emitter are swapped.


The value for this resistor can be calculated using the formula. Applications Can be used to switch high current upto mA loads It can also be used in the various switching applications.

When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter.

Javier Loureiro 1 7 Graf and William Sheets To confirm, you can double check with the datashet function if your meter has that.

The slightly lower of the two voltages will correspond to the collector-base junctionand the other will be the emitter-base junction. The 2N is considered a very common transistor, [1] [2] [3] and is used as an exemplar of an NPN transistor. It is used in a variety of analog amplification and switching applications. 2222a

All variations have a beta or current gain h fe of at least in optimal conditions. 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. Junkbots, bugbots, and bots on wheels: Absolute maximum rating for emitter-base voltage is 6V hence the E-B junction broke down and started conducting. Single transistors are also available in several different surface mount packages, and a number of manufacturers market surface mount packages that incorporate several 2Ntype transistors in one package as an array of transistors.

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. Retrieved 26 March The exact specifications depend on the manufacturer, case type, and variation. Use dmy dates from July Commons category link is on Wikidata. 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.


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.

2NA Pinout, Features, Equivalent & Datasheet

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

I have a simple circuit to send current to a datasheeg fan running at 12V on the high side, using a NPN transistor 2NA: Replacements for the 2N are commonly available now in the cheaper TO packaging, where it is known as the PN or P2N, which has similar specifications except for the lower maximum collector current.

This transistor will make it forward biased and thus closes the connection between collector and emitter.

If it is to datahseet a shorted transistor, we will never know if both are the same ebc configuration between your new 2N and the old 2N As the name suggests this resistor will limit the current flowing through the transistor to prevent it from damaging. Thank you for your interest in this question. The BC is a low voltage, low current, general-purpose switching transistor in a TO package.

It can be even worse, since the On Semi PN has the conventional pinout, despite being the same manufacturer and mostly same specifications:
