Datassheet Technical Details can be found at the 2NA datasheet given at the end of this page. Most 2Ns have the orientation which your diagram shows, where if the flat side is facing you, the pins are E-B-C respectively.

Spehro Pefhany k 4 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. 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 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. The value for this resistor can be calculated using the formula.

This transistor like all can be used either as a switch or as an amplifier. However one important thing to notice is the Base resistor a. Would I reuse it? Thank you for your interest in this question. TL — Programmable Reference Voltage.

I have a simple circuit to send current to a brushless fan running at 12V on the high datxsheet, using a NPN transistor 2NA: This transistor will make it forward biased and thus closes the connection between collector and emitter. You have to try each of the three pins to the two others, with both polarities 6 pairs of tests.

When datxsheet transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter.

So if you looking for an NPN transistor that could switch loads of higher current then 2NA might the right choice for your project. But there are two important features that distinguish both. I don’t think so – throw it in the bin.

What do datasheeet think? Datwsheet to use 2NA This transistor like all can be used either as a switch or as an amplifier. I have used a base voltage of 5V and a datashdet of 1K as current limiting resistor.

To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA. 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 adtasheet and emitter are swapped. Absolute maximum rating for emitter-base voltage is 6V hence the E-B junction broke down and started conducting. It can be even worse, since the On Semi PN has the conventional pinout, despite being the same manufacturer and mostly same specifications: To confirm, you can double check with the hFE function if your meter has that.

This is true of almost all modern transistors a few are made more symmetrical. I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA:.

Datashedt distinguish collector from emitter, you look at the voltage shown in the diode function with the one successful test that found the base. Applications Can be used to switch high current upto mA loads It can also be used in the various switching applications.

You can have up to 3 types of configurations.
