Junkbots, bugbots, and bots on wheels: The BC is a low voltage, low current, general-purpose switching transistor in a TO package. As the name suggests this resistor will limit the current flowing through the transistor to prevent it from damaging.

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 exact specifications depend on the manufacturer, case type, and variation. 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. As the name suggests this resistor will limit the current flowing through the transistor to prevent it from damaging.

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

The JEDEC registration of a device number ensures particular rated values will be met by all parts offered under that number. Wikimedia Commons has media related to 2N Single transistors are also available in several different surface mount packages, and a number tranzistor manufacturers market surface mount packages that incorporate several 2Ntype transistors in one package as an array of transistors.

The JEDEC registration of a device number ensures particular rated values will be met by all parts offered under that number. Most 2Ns have transidtor orientation which your diagram shows, where if the flat side is facing you, the pins are E-B-C respectively.

This page was last edited on 25 Octoberat Complete Technical Details can be found at the 2NA datasheet given at the end of this page. TL — Programmable Reference Voltage.

The general specifications of the various variants are similar, with the biggest difference being the maximum allowable current and power dissipation. By using this site, you agree to the Terms of Use and Privacy Policy. Retrieved 26 March High frequency and microwave engineering.

I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA: In other projects Wikimedia Commons. Transisotr Pefhany k 4 No transisgor pin will show that. 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. By using this site, you agree to the Terms of Use and Privacy Policy.

I have used a base voltage of 5V and a value of 1K as current limiting resistor. From Wikipedia, the free encyclopedia. Looking for a transistor? This transistor like all can be used either as a switch or as an amplifier. Other part numbers will have different parameters.

But there are two important features that distinguish both. Archived from the original on 14 April How to use 2NA This transistor like all can be used either as a switch or as an amplifier. The 2N is considered a very common transistor, [1] [2] [3] and is used as an exemplar of an NPN transistor.

When this 2222a is fully biased then it can allow a maximum of mA to flow across the collector and emitter. Learn to keep an eye open for the following transistors, as they’re among the most useful, inexpensive, and popular types: All variations have a beta or current gain h fe of at teansistor in optimal conditions.

It is frequently used as a small-signal transistor, [4] [5] and it remains a small general purpose transistor [6] of enduring popularity. Commercial transistors Bipolar tansistor. This is the picture of the datasheet for the pins: Applications Can be used to switch high current upto mA loads It can also be used in the various switching applications.

It was originally made in the TO metal trandistor as shown in the picture. 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. Find it and more at Jameco Electronics. You have to try each of the three pins to the two others, with both polarities 6 pairs of tests.

It is frequently used as a small-signal transistor, [4] [5] and it remains a small general purpose transistor [6] of enduring popularity. It is used in a variety of analog amplification and switching applications. Use dmy dates from July Commons category link is on Wikidata. So if you looking for an NPN transistor that trransistor switch loads of higher current then 2NA might the right choice for your project. Graf and William Sheets Zuofu 3, 2 15 Am I missing something here?

I have used a base voltage of 5V and a transisttor of 1K as current limiting resistor. The hFE is usually much higher when properly connected than when collector and emitter are swapped.

Build your own low-power transmitters: 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.
