Build your own low-power transmitters: In other projects Wikimedia Commons. How to use 2NA This transistor like all can be used either as a switch or as an amplifier.

To bias a transistor we have to supply current to base pin, this current I B datasheef be limited to 5mA.

The general specifications of the various variants are similar, with the biggest difference being the maximum allowable current and power dissipation. To make things simple I have shown a simplified circuit to dafasheet a transistor as switch. Applications Can be used to switch high current upto mA loads It can also be used in the various switching applications.

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. Archived from the original on 14 April So if you looking for an NPN transistor that could switch loads of higher current then 2NA might the right choice for your project.


Other part numbers will have different parameters. Junkbots, bugbots, and bots on wheels: Therefore, it is important to refer to the datasheet for the exact part number datasheett manufacturer.

2NA Pinout, Features, Equivalent & Datasheet

Retrieved 26 March Wikimedia Commons has media related to 2N The maximum amount of current that could flow through the Collector pin is mA, hence we 2h222 connect loads that consume more than mA using this transistor. It is designed for low to medium currentlow powermedium voltageand can operate at moderately high speeds.

They’re listed together because they’re complementary transistors. Retrieved from ” https: The JEDEC registration of a device number ensures particular rated values will be met by all parts offered under that number.

The exact specifications depend on the manufacturer, case type, and variation. Complete Technical Details can be found at the 2NA datasheet given at the end of this page.

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 2N is an NPN transistor that can only switch one-third the current of the 2N but has otherwise similar characteristics.

It was originally made in the TO metal can as shown in the picture. By using this site, you agree to the Terms of Use and Privacy Policy.


Commercial transistors Bipolar transistors. 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. The 2N is considered a very common transistor, [1] [2] [3] and is used as an exemplar of an NPN transistor.

In actual circuit modifications might be required. 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. Dtasheet this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter.

I have used a base voltage of 5V and a value of 1K as current limiting resistor. But there are two important features that distinguish both.

Replacements for the 2N are commonly available now in the cheaper TO packaging, where it is known as the PN or Datashee, which has similar specifications except for the lower maximum collector current.
