To distinguish collector from emitter, you look at the voltage shown in the diode function with the one successful test that found the base. To confirm, you can double check with the hFE function if your meter has that.

But there are two important features that distinguish both. No other pin will show that. Thank you for your interest in this question. The base will show a diode connection to both other pins, in only one polarity.

Note dxtasheet the motor here draws about mA from the 12V power source, since the 2N has collector current rating upto mA this datashee is possible had it been a BC the transistor should have been burnt. I have used a base voltage of 2222s and a value of 1K as current limiting resistor. In actual circuit modifications might be required. The hFE is usually much higher when properly connected than when collector and emitter are swapped. 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 I am trying to figure out what is going on here.

The slightly lower of the two voltages will correspond to the collector-base junctionand the other will be the emitter-base junction.

However one important thing to notice is the Base resistor a.

To make things simple I have shown a simplified circuit to make a transistor as switch. You have to datazheet each of the three pins to the two others, with both polarities 6 pairs of tests. Hence the 2N pin-out is sadly not standardized.

I don’t think so – throw it in the bin. This transistor like all can be used either as a switch or as an amplifier. The Base-Emitter voltage of this transistor is 6V so you just have to supply this voltage across the ratasheet and emitter of the transistor to induce a base current into the transistor.

Absolute maximum rating for emitter-base voltage is 6V hence the E-B junction broke down and started conducting. 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. Complete Technical Details can be found at the 2NA datasheet given at the end of this page.


So if you looking for an NPN transistor that could switch loads of higher current then 2NA might the right choice for your project. This is the picture of 2222q datasheet for the pins: As the name suggests this resistor will limit the current flowing through the transistor to prevent it from damaging. When Datasheer 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.

I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA: 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 value for this resistor can be calculated using the formula. Am I missing something ddatasheet TL — Programmable Reference Voltage.

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 I set up the circuit for a quick test, it seems that the datasheet or the transistor dataaheet the pins swapped. Javier Loureiro 1 7 Would I reuse it?
