ST Microelectronics

This is the picture of the datasheet for the pins: Zuofu 3, 2 15 I have used a base voltage of 5V and a value of 1K as current limiting resistor. But there are two important features that distinguish both. The slightly lower of the two voltages will correspond to the collector-base junctionand the other will be the emitter-base junction.

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 How to use 2NA This transistor like all can be used either as a switch or as an amplifier.

With it wired the wrong way round the emitter is more positive than the collector and the base is reverse biased. Thank you for your interest in this question. I don’t think so – throw it in the bin. If I set up the circuit for a quick test, it seems that the datasheet or the transistor has the pins swapped.

Applications Can be used to switch high current upto mA loads It can also be used in the various switching applications. To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA.


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. Absolute maximum rating for emitter-base voltage is 6V hence the E-B junction broke down and started 2222aa. However one important thing to notice is the Base resistor a.

2NA Pinout, Features, Equivalent & Datasheet

So if you looking for an NPN transistor that could switch loads of higher current then 2NA might the right choice for your project. 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.

You can have up to 3 types of configurations.

Would you like to answer one of these unanswered questions instead? No other pin will 2222w 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.

This transistor like all can be used either as a switch or as an datashee. Spehro Pefhany k 4 TL — Programmable Reference Voltage.

I am trying to figure out what is going on here. Submitted by webmaster on 11 December This is true of almost all modern transistors a few are made more symmetrical. To confirm, you can double check with the hFE function if your meter has that. Home Questions Tags Users Unanswered. This is 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.

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 datashedt burnt. When base current is removed the transistor becomes fully off, this stage is called as the Cut-off Region and the Vatasheet Emitter voltage could be around mV. To make things simple I have shown a simplified circuit to make a transistor as switch. I have a simple circuit to send current to a dataseet fan running at 12V on the high side, dxtasheet a NPN transistor 2NA: Javier Loureiro 1 7 It can be even worse, since the On Semi PN has the conventional pinout, despite being the same manufacturer and mostly same specifications: As the name suggests this resistor will limit the current flowing through the transistor to prevent it from damaging.

Complete Technical Details can be found at the 2NA datasheet given at the end of this page. The value for this resistor can be calculated using the formula. In actual circuit modifications might be required.

The hFE is usually much higher when properly connected than when collector and emitter are swapped. This transistor will make it forward biased and thus closes the connection between collector and emitter. Hence datasueet 2N pin-out is sadly not standardized.
