2NA Pinout, Features, Equivalent & Datasheet

They’re listed together because they’re complementary transistors. 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.

Complete Technical Details can be found at the 2NA datasheet given at the end of this page. This transistor will make it forward biased and thus closes the connection between collector and emitter. To distinguish collector from emitter, you look at the voltage shown in the diode function with the one successful test that found the base.

If it is to replace a shorted transistor, we will never know if both are the same ebc configuration between your new 2N and the old 2N Single transistors datashwet 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.

Submitted by webmaster on 11 December Therefore, it is important to refer to the datasheet for the exact part number and manufacturer. Learn to keep an eye open for the following transistors, as they’re among the most useful, inexpensive, and popular types: The exact specifications depend on the manufacturer, case type, and variation.

Hence the 2N pin-out is sadly not standardized. To confirm, you can double check with the hFE function if your meter has that.


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. Thank you for your interest in this question. Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site the association bonus does not count. Graf and William Sheets With it wired the wrong way round the emitter is more positive than the collector and the base is reverse biased.

Replacements for the 2N are commonly daasheet 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. It was originally made in the TO metal can as shown in the picture.

I don’t think so – throw it in the bin. How to use 2NA This transistor like all can be used either as a switch or as an amplifier. Archived from the original on 14 April High frequency and microwave engineering.

This is the pic of the transistor, as I understand that it should work, but it doesn’t it is always ‘on’ with 12V between the collector and the emitter with the base floating. 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 2n222 transistor should have been burnt. When this transistor is fully biased datasehet it can allow a maximum of mA to flow across the collector and emitter.

The 2N is considered a very common transistor, [1] [2] [3] and is used as an exemplar of an NPN transistor. The value for this resistor can be calculated using the formula. Would you like to answer one of these unanswered dztasheet instead?

So if you looking for an NPN transistor that could switch loads of higher current then 2NA might the right choice for your project. The 2N is an NPN transistor that can only switch one-third the current of the 2N but has otherwise similar characteristics. This is the picture of the datasheet for the pins: The base will show a diode connection to both other pins, in only one polarity.


I have used a base voltage of 5V and a value of 1K as current limiting resistor. It is used in a variety of analog amplification and switching applications. 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. Views Read Edit View history.

2N2222 Datasheet, Equivalent, Cross Reference Search

To make things simple I have shown a simplified circuit to make a transistor as switch. Would I reuse it? You can have up to 3 types of configurations. However one important thing to notice is the Base resistor a. Use dmy dates from July Commons category link is on Wikidata.

Retrieved 26 March From Wikipedia, the free encyclopedia. The general specifications of the various variants are similar, with the biggest difference being the maximum allowable current and 2n222w dissipation. Applications Can be used to switch high current upto mA loads It can also be used in the various switching applications. All variations have a beta or current gain h fe of at least in optimal conditions.
