However this vale will not be very accurate rtansistor the transistor will have an internal voltage drop across the collector current, so it mostly experimental to get the maximum current from the transistor. Where Vcc is the voltage on which the load operates and V BE is the voltage across the Base and Emitter which in our case according to the data sheet 1.

TL — Programmable Reference Voltage. Complete Technical Details can dtaasheet found at the datasheet given at the end of this page.

But it comes in a metal can package and can operate on voltages slightly higher than what a 2N can handle. Another important thing to keep in mind, while using a transistor as switch is the base resistor. Here lets us assume the load here consumes around mA maximum so our collector current I C mA.


So the value if R B will be. Current Drains out through emitter, normally connected to ground.

Where h FE, is the current gain of the transistor which in our case is Since transistor is of NPN the load to be switched should be connected to the collector and the emitter should be connected to the ground as show in the figure below. To make this current flow through the transistor the value of base current I B can be calculated using the below formula:.

Submitted by admin on 21 June So if you looking for an NPN transistor that dataseet switch loads or for decent amplification then 2N might the right choice for your project. The 2N is a NPN transistor and is normally used as a switch in many circuits. This resistor is connected to the base pin of the transistor to limit the current flowing through the base.

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

Overall it is just another small signal transistor which is commonly used in datashret and amplifying circuits. Amplifier modules like Audio amplifiers, signal Amplifier etc.

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. This stage is called Saturation Region. The value of this datasheeet can be calculated by the required amount of current that will be consumed by the load.


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 to calculate the resistor value of the base we can use the formulae. Current flows in through collector, normally connected to load.

To make this current flow through the transistor the value of base current I B can be calculated using the below formula: As we know the transistor is a current controlled device meaning, we have pass some current I B thorough the base of the transistor to turn it on.

In our case for a collector current of mA we have to pass a base current of 16mA. But this calculation will lead to the closest value to start with. To bias a transistor we have transistir supply current to base pin, this current I B should be limited to 5mA by using a transistor to the base pin.
