When base current is removed the transistor becomes datasehet off, this stage is called as the Cut-off Region and the Base Emitter voltage could be around mV. 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.

Current flows in through collector, normally connected to load. Amplifier modules like Audio amplifiers, signal Amplifier etc. But this calculation will lead to the closest value to start with.

But it comes in a metal can package and can operate on voltages slightly higher than what a 2N can handle. Overall it is just another small signal transistor which is commonly used in switching and amplifying circuits.

So if you looking for an NPN transistor that could switch loads or for decent amplification then 2N might the right choice for your project. Datashee 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.

To bias a transistor we have to supply current to base pin, this current I B should be limited to 5mA by using a transistor to the base pin. To make this current flow through the transistor the value of base current I Dahasheet can be calculated using the below formula: TL — Programmable Reference Voltage.

The maximum amount of dataeheet 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 datasheet given at the end of this page. This stage is called Saturation Region.

The value dataaheet this current can be calculated by the required amount of current that will be consumed by the load. However this vale will not be very accurate because the transistor will have an internal voltage drop across the collector current, so it mostly experimental to get the maximum current from the transistor. To make this current flow through the transistor the value of base current I B can be calculated using the below formula:.

Another important thing to keep in mind, while using a transistor as switch is the base resistor.

So the value if R B will be. 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. In our case for a collector current of mA we have to pass a base current of 16mA.

Where h Dahasheet, is the current gain of the transistor which in our case is Here lets us assume the load here consumes around mA maximum so our collector current I C mA. This resistor is connected datahseet the base pin of the transistor to limit the current flowing through the base.

Submitted by admin on 21 June The 2N is a NPN transistor and is normally used as a switch in many circuits. So to calculate the resistor value of the base we can use the formulae. When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter.

Current Drains out through emitter, normally connected to ground.
