The value for this resistor can be calculated using the formula. 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.
So if you looking for an NPN transistor that could switch loads of higher current then 2NA might the right choice for your project. Vatos that the motor here vatos 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. I have used a base voltage of 5V and a value of 1K as current limiting resistor. 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.
But there are two important features that distinguish both. Complete Technical Details can be found at the 2NA datasheet given 2n the end of this page. To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA. As the name suggests this resistor will limit the current flowing through the transistor to prevent it from damaging. Submitted by webmaster on 11 December When this transistor is fully biased then it can allow a maximum of mA to flow across 2n collector and emitter.

The BC is a low voltage, low current, general-purpose switching transistor in a TO package. Buyers may be subject to sott23 charges for customs clearance. Retrieved 26 March Single transistors are also available in several different surface mount packages, and a number of manufacturers market surface mount packages that incorporate several 2Ntype transistors in one package as an array of transistors.
