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.

I am trying to figure out what is going on here. It is designed for low to medium currentlow powermedium voltageand can operate at moderately high speeds. 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 datasheer has the pins swapped.
Hence the 2N pin-out is sadly not standardized. 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. 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 datahseet.
No other pin will show that.

Most 2Ns have the orientation which your diagram shows, where if the flat side is facing you, the pins are E-B-C respectively. It is frequently used as a small-signal transistor,   and it remains a small general purpose transistor  of enduring popularity.
Applications Can be used to switch high current upto mA loads It can also be used in the various switching applications. Would you like to answer one of these unanswered questions instead? 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 don’t think so – throw it in the bin.

I have a simple circuit to send current to a brushless fan running at 12V on the high side, using a NPN transistor 2NA: The situation worsen when all these china fake transistors crowded the whole market, there are no standardization at all. But there are two important features 2222a distinguish both.
However one important thing to notice is the Base resistor a. Other part numbers will have different parameters. Graf and William Sheets The 2N, 2N, and 2N devices, for example, which date back to the datawheet but have been improved, are still useful in new designs and are still popular for experimenters.
The exact specifications depend on the manufacturer, case type, and variation. The general specifications of the various variants are similar, with the biggest difference being the maximum allowable current and power dissipation.
It can be even worse, since the 222a2 Semi PN has the conventional pinout, despite being the same manufacturer and mostly same specifications: From Wikipedia, the free encyclopedia. In actual circuit modifications might be required. As the name suggests this resistor will limit the current flowing through the transistor to prevent it from damaging.
