This page datashet last edited on 25 Octoberat Build your own low-power transmitters: When base current is removed the transistor becomes fully off, this stage is called as the Cut-off Region and the Base Emitter voltage could be around mV.

The BC is a low voltage, low current, general-purpose switching transistor in a TO package. Billions of units have been manufactured over the past 45 years and there is continuing high volume annual datasheeg.

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. I have used a base voltage of 5V and a value of 1K as current limiting resistor. Complete Technical Details can be found at the 2NA datasheet given at the end of this page.

2NA Pinout, Features, Equivalent & Datasheet

The maximum amount of current that could flow datasueet the Collector pin is mA, hence we cannot connect loads that consume more than mA using this transistor. Therefore, it is important to refer to the datasheet for the exact part number and manufacturer.

To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA. The datashet specifications of the various variants are similar, with the biggest difference being the maximum allowable current and power dissipation.

Views Read Edit View history. It is frequently dxtasheet as a small-signal transistor, [4] [5] and it remains a small general purpose transistor [6] of enduring popularity. From Wikipedia, the free encyclopedia. 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.

Submitted by dagasheet on 11 December The 2N exhibits its forward gain beta 2nn222 at a lower current than the 2N, and is useful in amplifier applications with reduced I ce. The value for this resistor can be calculated using the formula. The exact specifications depend on the manufacturer, case type, and variation.

It was originally made in the TO metal can as shown in the picture. All variations have a beta or current gain h fe of at least in optimal conditions. 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. When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter.

Retrieved 26 March 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: Wikimedia Commons has media related to 2N However one important thing to notice is the Base resistor a.

The 2N is considered a very common transistor, [1] [2] [3] and is used as an exemplar of an NPN transistor. JEDEC registered parameters daasheet 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, 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.

It is designed for low to medium currentdtaasheet powermedium voltageand can operate at moderately high speeds. By using this site, you agree to the Terms of Use and Privacy Policy. This transistor like all can be used either as a switch or as an amplifier. Applications Can be used to switch high current upto mA loads It can also be used in the various switching applications. Graf and Datazheet Sheets In other projects Datasheeh Commons. Junkbots, bugbots, and bots on wheels: 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. Commercial transistors Bipolar transistors. The 2N is an NPN transistor that can only switch one-third the current of the 2N but has otherwise similar characteristics. In actual circuit modifications might be required.

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. How to use 2NA This transistor like all can be used either as a switch or as an amplifier. TL — Programmable Reference Voltage.

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

But there are two important features that distinguish both. Retrieved from ” https: They’re listed together because they’re complementary transistors. To make things simple I have shown a simplified circuit to make a transistor as switch. This transistor will make it forward biased and thus closes the connection between collector and emitter.
