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. Views Read Edit View history. The value for this resistor can be calculated using the formula. I have used a base voltage of 5V and a value of 1K as current limiting resistor. Submitted by webmaster on 11 December If it is to replace a shorted dahasheet, we will never know if both are the same ebc configuration between your new 2N and the old 2N Am I missing something here?

Billions of units have been manufactured over the past 45 years and there is continuing high volume annual production. daatasheet

I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA:. This transistor like all can be used either as a switch or as an amplifier.

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.

The BC is a low voltage, low current, general-purpose switching transistor in a TO package. This transistor will make it forward biased and thus closes the connection between collector and emitter. Typical examples are the well known NPN and PNP industrial and military types, 2N and 2N, which have been used for over datasbeet decades and are still being used in many designs.

To confirm, you can double check with the datzsheet function if your meter has that.

If I set up the circuit for a quick test, it seems that the datasheet or the transistor has the pins swapped. When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter.

To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA. Learn to keep an eye open for the following transistors, as they’re among the most useful, inexpensive, and popular types: 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.

TL — Programmable Reference Voltage. 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. But there are two important features that distinguish both. This page was last edited on 25 Octoberat They’re listed together because they’re complementary transistors.

In actual circuit modifications might be required. Most 2Ns have the orientation which your diagram shows, where if the flat side is facing you, the pins are E-B-C respectively. It is frequently used as a small-signal transistor, [4] [5] and it remains a small general purpose transistor [6] of enduring popularity.

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.

The general specifications of the various variants are similar, with the biggest difference being the maximum allowable current and power dissipation. 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 JEDEC registration of a device number ensures particular rated 2222z will be met by all parts offered under that datahseet. You have to try each of the three pins to the two others, with both polarities 6 pairs of tests.

How to use 2NA This transistor like all can be used either as a switch or as an amplifier. I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA: It is designed for low to medium currentlow powermedium voltageand can operate at moderately high speeds. However one important thing to notice is the Base resistor a. You can have up to 3 types of configurations.

The hFE is usually datashewt higher when properly connected than when collector and emitter are swapped. Junkbots, bugbots, and bots on wheels: I am trying to figure out what is going on here. Use dmy dates from July Commons category link is on Wikidata. 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, even when the base has no voltage pulled down or floatingand the transistors gets pretty hot.
