This transistor like all can be used either as a switch or as an amplifier.
However one important thing to notice is the Base resistor a. I have used a base voltage of 5V and a value of 1K as current datasheet resistor.
The maximum bc1087 of current that could flow through the Collector pin is mA, hence we cannot connect loads that consume more than mA using this transistor. Submitted by webmaster on 11 December To make things simple I have shown a simplified circuit to make a transistor as switch.
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. Note that the motor here draws about mA from datasueet 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.
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 datasheef will limit the current flowing through the transistor to prevent it from damaging.
How to use 2NA This transistor like all can be used either as a switch or as an amplifier.
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 Base-Emitter voltage of this transistor is 6V so you just have to supply this voltage across the base and emitter of adtasheet transistor to induce a base current into the transistor.
Applications Can be used to switch high current upto mA loads It can also be used in the various switching applications. This transistor will make it forward biased and thus closes the connection between collector and emitter.
Complete Technical Details can be found at the 2NA datasheet given at the end of this page. In actual circuit modifications might be required.
But there are two important features that distinguish both. TL — Programmable Reference Voltage. When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter. Dataasheet value for this resistor can be calculated using the formula.
