Spehro Pefhany k 4 It can be even worse, since the On Semi PN has the conventional pinout, despite being the same manufacturer and mostly same specifications: Home Questions Tags Users Unanswered.

Would you like to answer one of these unanswered questions instead?

I don’t think so – throw it in the bin. Am I missing something here?

Korea Electronics (KEC)

I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA: Absolute maximum rating for emitter-base voltage is 6V hence the E-B junction broke down and started conducting.

With it wired the wrong way round the emitter is more positive than the collector catasheet the base is reverse biased. Zuofu 3, 2 15 Try not to touch the transistor while testing it because temperature will dataxheet the voltage readings.

Would I reuse it? What do you think? Javier Loureiro 1 7 It looks like a “diode”. The slightly lower of the two voltages will correspond to the collector-base junctionand the other will be the emitter-base junction. The hFE is usually much higher when properly connected than when collector and emitter are swapped.

Thank you for your interest in this question. This jn2222 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.

If I set up the circuit for a quick test, it seems that the datasheet or the transistor has the pins swapped. To distinguish collector from emitter, you look at the voltage shown in the diode function with the one successful test that found the base.

This is the picture of the datasheet for the pins: The base will show a diode connection to both other pins, in only one polarity.

When I apply a voltage dataseet 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. No other ,n2222 will show that.


Hence the 2N pin-out is sadly not standardized. To confirm, you can datsaheet check with the hFE function if your meter has that. The situation worsen when all these china fake transistors crowded the whole market, there are no standardization at all. You have to try each of the three pins to the two others, with both polarities 6 pairs of tests. You can have up to 3 types of configurations.

I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA:. If it is to replace a shorted transistor, we will never know if both are the same ebc configuration datashee your new 2N and the old 2N This is true of almost all modern transistors a few are made more symmetrical.

Because it has attracted low-quality or spam answers that had to be removed, posting an dafasheet now requires 10 reputation on this site the association bonus does not count. Most 2Ns have the orientation which your diagram shows, where if the flat side is facing you, the pins are E-B-C respectively.

I am trying to figure out what is going on here.
