So the value if R B will be. Submitted by admin on 21 June dataaheet To make this current flow through the transistor the value of base current I B can be calculated using the below formula: Amplifier modules like Audio amplifiers, signal Amplifier etc.

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.

Another important thing to keep in mind, while using a transistor as switch is the base resistor. 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. The value of this current can be calculated by the required amount of current that will be consumed by the load. Here lets us assume the load here consumes around mA maximum so our collector current I C mA.


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. 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 n22219 the figure below.

Complete Technical Details can be found at the datasheet given at the end of this page. This resistor is connected to the base pin of the transistor to limit the current flowing through the base. So to calculate the resistor value of the base we can use the formulae. Current flows in through collector, normally connected to load.

But it comes in a hransistor can package and can operate on voltages slightly higher than what a 2N can handle. 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 make this current flow through the transistor the value of base current I B can be calculated using the below formula:. 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 daatasheet maximum current from the transistor.


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. Overall it is just another small signal transistor which is commonly used in switching and amplifying circuits. Where h FE, is the current gain of the transistor which in our case is 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.

The 2N is a NPN transistor and is normally used as a switch in many 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. When this transistor is fully biased then it can allow a maximum of mA transisstor flow across the collector and emitter. TL — Programmable Reference Voltage.

Current Drains out through emitter, normally connected to ground.
