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. Current Drains out through emitter, normally connected to ground.
The 2N is a NPN transistor and is normally used as a datqsheet in many circuits. Amplifier modules like Audio amplifiers, signal Amplifier etc.

But it comes in a metal can package and can operate on voltages slightly higher than dataseet a 2N can handle. TL — Programmable Reference Voltage. So to calculate the resistor value of the base we 2n229 use the formulae.
But this calculation will lead to the closest value to start with. When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter.
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. Here lets us assume xatasheet load here consumes around mA maximum so our collector current I C mA. Where h FE, is the current gain of the transistor which in our case is As we know the transistor is a current controlled device meaning, we have pass some current I B thorough the base of the transistor transisto turn it on.

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. Current flows in through collector, normally connected to 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 if you looking for an NPN transistor that could switch loads or for tranisstor amplification then 2N might the right choice for your project. However this vatasheet 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.

In our case for a collector current of mA we trnsistor to pass a base current of 16mA. This stage is called Saturation Region. Another important thing to keep in mind, while using a transistor as switch is the base resistor.
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: To make this current flow through the transistor the value of base current I B can be calculated using the below formula:.
Overall it is just another small signal transistor which is commonly used in switching and amplifying circuits. Submitted by admin on 21 Transjstor This resistor is connected to the base pin of the transistor to limit the current flowing through the base.
The value of this current can be calculated by the required amount of current that will be consumed by the load. So the value if R B will be.
