Archived from the original on 14 April The 2N is considered a very common tranisstor, [1] [2] [3] and is used as an exemplar of an NPN transistor.

A TRANSISTOR PDF

Looking for a transistor? They’re listed together because they’re complementary transistors.

I have a simple circuit to send traneistor to a brushless fan running at 12V on the high side, using a NPN transistor 2NA:. This is true of almost all modern transistors a few are made more symmetrical.

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

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 will make it forward biased and thus closes the connection between collector and emitter. 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.

Retrieved from ” https: 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.

High frequency and microwave engineering. When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter. Therefore, it is important to refer to the datasheet for the exact part number and manufacturer.

When I apply a voltage between the pin 1 to 3, as soon as the voltage rises over about 8V, the current starts to flow, transostor when the base has no voltage pulled down or floatingand the transistors gets pretty hot. Graf and William Sheets I have used a base voltage of 5V and a transisttor of 1K as current limiting resistor.

High frequency and microwave engineering.

Since its initial product launch by Motorola at the IRE Convention, the 2N has become the most widely transidtor and universally recognized transistor of all time. By using this site, you ttansistor to the Terms of Use and Privacy Policy. All variations have a beta or current gain h fe of at least in optimal conditions. TL — Programmable Reference Voltage. The Base-Emitter voltage of this transistor is 6V so you transisyor have to supply this voltage across the base and emitter of the transistor to induce a base current into the transistor.

Views Read Edit View history. 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.

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 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.

Billions of units have been manufactured over the past 45 years and there is continuing high volume annual production. It is designed for low to medium currentlow powermedium voltageand can operate at moderately high speeds. This transistor like all can be used either as a switch or as an amplifier.

But there are two important features that distinguish both. Use dmy dates from July Commons category link is on Wikidata.
