Complete Technical Details can be found at the 2NA datasheet given at the end of this page. 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.
Submitted by webmaster 2222a 11 December Absolute maximum rating for emitter-base voltage is 6V hence the E-B junction broke down and started conducting. Try not to touch the transistor while testing it because temperature will change the voltage datashwet.
To make things simple I have shown a simplified circuit to make a transistor as switch. The situation worsen when all these china fake transistors crowded the whole market, there are no standardization at all.
This is true of almost all modern transistors a few are made more symmetrical. Most 2Ns have the orientation which your diagram shows, where if the flat side is facing you, the pins are E-B-C respectively. I am trying to figure out what is going on here.

As the name suggests this resistor will limit the current flowing through the transistor to prevent it from damaging. I have used a base voltage of 5V and a value of 1K as current limiting resistor.
When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter. Would you like to answer one of these unanswered questions instead?
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 Datashest the transistor should have been burnt. Applications Can be used to switch high current upto mA loads It can also be used in the various switching applications.
This transistor like all can be used either as a switch or as an amplifier.
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.
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.
Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires datashewt reputation on this site the association bonus does not count.
The value for this resistor can be calculated using the formula. I don’t think so – throw it in the bin. Zuofu 3, 2 15 The hFE is usually much higher when properly connected than when collector and emitter dataseet swapped. Home Questions Tags Users Unanswered. No other pin will show that. In actual circuit modifications might be required.
To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA. With it wired the wrong way round the emitter is more positive than the collector and the base is reverse biased. This transistor will make it forward biased and thus closes the connection between 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.
