Hence the 2N pin-out is sadly not standardized. But there are two important features that distinguish both. I have a simple circuit to send current to a datashest fan running at 12V on the high side, using a NPN transistor 2NA:. Thank you for your interest in this question. 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.
As the name suggests this resistor will limit the current flowing through the transistor to prevent it from damaging. I am trying to figure out what is going on here.
Complete Technical Details can be found at the 2NA datasheet given at the end of this page. TL — Programmable Reference Voltage.
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. 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 pic of the transistor, as I understand that it should work, but it doesn’t it datashete always ‘on’ with 12V between the collector and the emitter datasheeh the base floating.
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. 2222a it wired the wrong way round the emitter is more positive than the collector and the base is reverse biased.

This transistor like all can be used either as a switch or as an amplifier. In actual circuit modifications might be required. Absolute maximum rating for emitter-base voltage is 6V hence the E-B junction broke down and started conducting. Home Questions Tags Users Unanswered.
I don’t think so – throw it in the bin. 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. Would I reuse it? What do you think? The value for this resistor can be calculated using the formula. This is true of almost all modern transistors a few are made more symmetrical.
2NA Pinout, Features, Equivalent & Datasheet
I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA: This is the picture of the datasheet for the pins: No other pin will show that.
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.
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. How to use 2NA This transistor like all can be used either as a switch or as an amplifier.
Spehro Pefhany k 4 To confirm, you can double check with the hFE function if your meter has that. So if you looking for an NPN transistor that could switch loads of higher current then 2NA might the right choice for your project. However one important thing to notice is the Base resistor a. This transistor will make it forward biased and thus closes the connection between collector and emitter.
