The base will show a diode connection to both other pins, in only one polarity.

Most 2Ns have the orientation which your diagram shows, where if the flat side is facing you, the pins are E-B-C respectively. The slightly lower of the two voltages will correspond to the collector-base junctionand the other will be the emitter-base junction.

This transistor will make it forward biased and thus closes the connection between collector and emitter. When base current is removed the transistor becomes fully off, this stage is called as the Cut-off Region and the Base Emitter voltage could be around mV.

It can be even worse, since the On Semi PN has the conventional pinout, despite being the same manufacturer and mostly same specifications: 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 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 is true of almost all modern transistors a few are made more symmetrical. Zuofu 3, 2 15 As the name suggests this resistor will limit the current flowing through the transistor to prevent it from damaging. This is the picture of the datasheet for the pins: Home Questions Tags Users Unanswered.

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

What do you think? But there are two important features that distinguish both. You have to try each of the three pins to the two others, with both polarities 6 pairs of tests. To bias a transistor we have to supply current to base pin, datashfet current I B should be limited to 5mA. If I set up the circuit for a quick test, it seems that the datasheet or the transistor has the pins swapped.

Would I reuse it? If it is to replace a shorted transistor, we will never know if both are the same ebc configuration between your datasehet 2N and the old 2N How to use 2NA This transistor like all can be used either as datashewt switch or as an amplifier.

To distinguish collector from emitter, you look at the voltage shown in the diode function with the one successful test that found the base. I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN 2222z 2NA:. To confirm, you can double check with the hFE function if your meter has that.

Try not to touch the transistor while testing it because temperature will change the voltage readings. Thank you for your interest in this question.

So if you looking for an NPN transistor that could switch loads of higher current then 2NA might the right choice for your project. I am trying to figure out what is going on here. 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.

Spehro Pefhany k 4 Hence the 2N pin-out is sadly not standardized. Absolute maximum rating datasheeh emitter-base voltage is 6V hence the E-B junction broke down and started conducting.
