The exact specifications depend on the manufacturer, case type, and variation. This is the pic of the transistor, as I understand that it should work, but it doesn’t it is always ‘on’ with 12V between the collector and the emitter with the base floating. The 2N, 2N, and 2N devices, for example, which date back to the s but have been improved, are still useful in new designs datwsheet are still popular for experimenters. From Wikipedia, the free encyclopedia. You can have up to 3 types of configurations.

If it is to replace a shorted transistor, we will never know if both are the same ebc configuration between your new 2N and the old 2N Archived from the original on 14 April I am trying to figure out what is going on here.

However one important thing to notice is the Base resistor a. This is the picture of the datasheet for the pins: Retrieved from ” https: To confirm, you can double check with the hFE function if your meter has that. It is used in a variety of analog amplification and switching applications. I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA:. Use dmy dates from July Commons category link is on Wikidata.

When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter. The 2N is considered a very common transistor, [1] [2] [3] and is used as an exemplar of an NPN transistor.

This page was last edited on 25 Octoberat Zuofu 3, 2 15 The base datwsheet show a diode connection to both other pins, in only one polarity. The general specifications of the various variants are similar, with the biggest difference being the maximum allowable current and power dissipation. It looks like a “diode”. The BC is daasheet low voltage, low current, general-purpose switching transistor in a TO package.

Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site the association bonus does not count.

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. JEDEC registered parameters include outline dimensions, small-signal current gaintransition frequencymaximum values for voltage withstand, current rating, power dissipation and temperature rating, and others, datasheet under standard test conditions.

I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA: Complete Technical Details can be found at the 2NA datasheet given at the end of this page. 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.

As the name suggests this resistor will limit the current flowing through datasheer transistor to prevent it from damaging.

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.

Would you like to answer one of these unanswered questions instead? When I apply a voltage between the pin 1 to 3, as soon as the voltage rises over about 8V, the datzsheet starts to flow, even when the base has no voltage pulled down or floatingand the transistors gets pretty hot.

Applications Can be used to switch high current upto mA loads It can also be used in the various switching applications. It is designed for low to medium currentlow powermedium voltageand can operate at moderately high speeds. Javier Loureiro 1 7 The situation worsen when all these china fake transistors crowded satasheet whole market, there are no standardization at all.

But there are two important features that distinguish both. If I set up the circuit for a quick test, it seems that the datasheet or the transistor has the pins swapped. Billions of units have been manufactured over the past 45 years and there is continuing high volume annual production. How to use 2NA This transistor like all can be used either as a switch or as an amplifier. The JEDEC registration of a device number ensures particular rated values will be met by all parts offered under that number.

Retrieved 26 March datashwet Most 2Ns have the orientation which your diagram shows, where if the flat side is facing you, the pins are E-B-C respectively. Am I missing something here? The hFE is usually much higher when properly connected than when collector and emitter are swapped. Hence the 2N pin-out is sadly not standardized.
