Zuofu 3, 2 transitor Am I missing something here? When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter.

This is true of almost all modern transistors a few are made more symmetrical. Graf and William Sheets Single transistors are also available in several transistr 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.

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. 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.

Billions of units have been manufactured over the past 45 years and there is continuing high volume annual production. Views Read Edit View history. Note that the motor here draws about mA from the 12V power source, since the 2N has collector current rating 2222a mA this circuit is possible had it been a BC the transistor should have been burnt.

High frequency and microwave engineering. The 2N is considered a very common transistor, [1] [2] [3] and is used as an exemplar of an NPN transistor. How to use tarnsistor 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.

The 2N is an NPN transistor that can only switch one-third the current of the 2N but has otherwise similar characteristics. When base current is removed the transistor becomes fully off, this trxnsistor is called as the Cut-off Region and the Base Emitter voltage could be around mV.

By using this site, you agree to the Terms of Use and Privacy Policy. 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. Retrieved 26 March 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.

I have used a base voltage of 5V and a transisttor of 1K as current limiting resistor. By using this site, you agree to the Terms of Use and Privacy Policy. High frequency and microwave engineering. Looking for a transistor? 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.

It is frequently used as a small-signal transistor, [4] [5] and it remains a small general purpose transistor [6] of enduring popularity.

Complete Technical Details can be found at the 2NA datasheet given 2222aa the end of this page. As the name suggests this resistor will limit the current flowing transistog the transistor to prevent it from damaging. Therefore, it is important to refer to the datasheet for the exact transisstor number and manufacturer. Commercial transistors Bipolar transistors. Spehro Pefhany k 4 No transisgor pin will show that. Most 2Ns have transidtor orientation which your diagram shows, where if the flat side is facing you, the pins are E-B-C respectively.

From Wikipedia, the free encyclopedia. This page was last edited on 25 Octoberat However one important thing to notice is the Base resistor a. 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. All variations have a beta or current gain h fe of at least in optimal conditions.

The exact specifications depend on the manufacturer, case type, and variation. Learn to keep an eye open for the following transistors, as they’re among the most useful, inexpensive, and popular types: It is frequently used as a small-signal transistor, [4] [5] and it remains a small general purpose transistor [6] of enduring popularity. This transistor like all can be used either as a switch or as an amplifier.

What do you think? 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.

I have used a base voltage of 5V and a value of 1K as current limiting resistor. 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.

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. 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.

When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter.
