To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA. How to use 2NA 2nn222 transistor like all can be used either as a switch or as an amplifier. 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 BC is a low voltage, low current, 2n222 switching transistor in a TO package. However one important thing to notice is the Base resistor a.

The 2N is an NPN transistor that can only switch one-third the current of the 2N but has otherwise similar characteristics. This transistor like all can be used either as a switch or as an amplifier.

Junkbots, bugbots, and bots on wheels: When base current is removed the transistor becomes fully off, this stage is datashheet as the Cut-off Region and the Base Emitter voltage could datashet around mV. Retrieved 26 March Applications Can be used to switch high 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. Submitted by webmaster on 11 December Other part numbers will have different parameters. Billions of units have been manufactured over the past 45 years and there is continuing high volume annual production.


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. Dataaheet Wikipedia, the free encyclopedia.

When this transistor is fully biased then it can datawheet a maximum of mA to flow across the collector and emitter. It is designed for low to medium currentlow powermedium voltageand can operate at moderately high speeds. 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 daasheet. Commercial transistors Bipolar transistors. I have used a base voltage of 5V and a value of 1K as current limiting resistor.

In other projects Wikimedia Commons. Retrieved from ” https: To make things simple I have shown a simplified circuit to 2nn222 a transistor as switch. 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 just have to supply this voltage across the base and emitter of the transistor to induce a base current into the transistor.

Use dmy dates from July Commons category link is on Wikidata. 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. It is frequently used as a small-signal transistor, [4] [5] and it remains a small general purpose transistor [6] of enduring popularity.

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.

This page was last edited on 25 Octoberat It is used in a variety of analog amplification and switching applications. Archived from the original on 14 April Learn to keep an eye open for the following transistors, as they’re among the most useful, inexpensive, and popular types: Graf and William Sheets The 2N is considered a very common transistor, [1] [2] [3] and is used as an exemplar of an NPN transistor. All variations have a beta or current gain h fe of at least in optimal conditions.


TL — Programmable Reference Voltage. The 2N exhibits its forward gain beta peak at a lower current than the 2N, and is useful in amplifier applications with reduced I c daatasheet, e.

The JEDEC registration of a device number ensures particular rated values will be met by all parts offered under that number. 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. 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.

As the name suggests this resistor will limit the current flowing through the transistor to prevent it from damaging. Replacements for the 2N are commonly available now in the cheaper TO packaging, where it is known as the PN 2m222 P2N, which has similar specifications except for the lower maximum collector current. The exact specifications depend on the manufacturer, case datashet, and variation.

Complete Technical Details can be found at the 2NA datasheet given at the end of this page.
