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 The 2N is an NPN transistor that can only switch one-third the current of the 2N but has otherwise similar characteristics. 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.

Home Questions Tags Users Unanswered. I don’t think so – throw it in the bin. 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.
This page was last edited on 25 Octoberat Retrieved 26 March I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA:. Zuofu 3, 2 15 The BC is a low voltage, low current, general-purpose switching transistor in a TO package. From Wikipedia, the free encyclopedia. Retrieved from ” https: No other pin will show that. I am trying to figure out what is going on here.
The hFE is usually much higher when properly connected than when collector and emitter are swapped. In actual circuit modifications might be required. The JEDEC registration of a device number ensures particular rated values will be met by all parts offered under that number.
Javier Loureiro 1 7 Most 2Ns have the orientation which your diagram shows, where if the flat side is facing you, the pins are E-B-C respectively. You have dtasheet try each of the three pins to the two others, with both polarities 6 pairs of tests. Junkbots, bugbots, and bots on wheels: The base will show a diode connection to both other pins, in only one polarity.
Commercial transistors Bipolar transistors. It is designed for low to medium currentlow powermedium voltageand can operate at moderately high speeds. Other part numbers will have different parameters. Datashet the 2N pin-out is sadly not standardized.
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. All variations have a beta or current gain h fe of at least in optimal conditions. Spehro Pefhany k 4 JEDEC registered parameters include outline dimensions, small-signal current gaintransition frequencymaximum values for voltage withstand, datashete 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. Wikimedia Commons has media related to 2N What do you think?
Graf and William Sheets Would you like to answer one of these unanswered questions instead? Views Read Edit View history. It is used in a variety of analog amplification and switching applications.
The situation worsen when all these china fake transistors crowded the whole market, there are no standardization at all. The exact specifications depend on the manufacturer, case type, and variation. 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.
2NA Pinout, Features, Equivalent & Datasheet
Archived from the original on 14 April If I set up the circuit for a quick test, it seems that the datasheet or the transistor has the pins swapped. The slightly lower of the two voltages will correspond to the collector-base junctionand the other will be the emitter-base junction. 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.
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. The 2N is considered a very common transistor,    and is used as an exemplar of an NPN transistor.
Datwsheet transistor will make it forward biased and fatasheet closes the connection between collector and emitter. When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter.
Applications Can be used to switch high current upto mA loads It can also be used in the various switching applications. To distinguish collector from emitter, you look at the voltage shown in the diode function with the one successful test that found the base.
So if you looking for an NPN transistor that could switch loads of higher current then 2NA might the right choice for your project. To confirm, you can double check with the hFE function if your meter has that.
When Datasheeg apply a voltage between the pin 1 to 3, as soon as the voltage rises over datssheet 8V, the current starts to flow, even when the base has no voltage pulled down or floatingand the transistors gets pretty hot.
Therefore, it is important to refer to the datasheet datasyeet the exact part number and manufacturer.
