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

This transistor like all can be used either as a switch or as an amplifier. How to use 2NA This transistor like all can be used either as a switch or as an amplifier. Applications Can be used to switch high current upto mA loads It can also be used in the various switching applications.

However one important thing to notice is the Base resistor a. As the name suggests this resistor will limit the current flowing through the transistor to prevent it from damaging.

When base current is removed the transistor becomes fully off, this stage is 2nn2222 as the Cut-off Region and the Base Emitter voltage could be around mV. TL — Programmable Reference Voltage. 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.

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. I have used a base voltage of 5V and a value datow 1K as current limiting resistor.

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 dqtos been burnt. Submitted by webmaster on 11 December So if you looking for an NPN transistor that could switch loads of higher current then 2NA might the right choice for your project.

In actual circuit modifications might be required. 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.

This transistor will make it forward biased and thus closes the connection between collector and emitter. But there are two important features that distinguish both.

To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA. To make things simple I have shown a simplified circuit to make a transistor as dtaos.
