Complete Technical Details can be found at the datasheet given at the end of this page.

To make this current flow through the transistor the datwsheet of base current I B can be calculated using the below formula:. Submitted by admin on 21 June When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter.

Amplifier modules like Audio amplifiers, signal Amplifier etc. So to calculate the resistor value of the base we can use the formulae. Since transistor is of NPN the load 2n22199 be switched should be dafasheet to the collector and the emitter should be connected to the ground as show in the figure below. 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.


Overall it is just another small signal transistor which is commonly used in switching and amplifying circuits. 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. Here lets us assume the load here consumes 2b2219 mA maximum so our collector current I C mA. But this calculation will lead to the closest value to start with.

Current Drains out through emitter, normally connected to ground. The maximum amount of current datashedt could flow through the Collector pin is mA, hence we cannot connect loads that consume more than mA using this transistor. Current flows in through collector, normally connected to load.

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 datassheet current flowing through the base. 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.

In our case for a collector current of mA we have to pass a base current of 16mA. 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.


Where h FE, is the current gain of the transistor which in our case is TL — Programmable Reference Voltage. But it comes in a metal can package and can operate on voltages slightly higher than what a 2N can handle.

The value of this current 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 datashfet the Base Emitter voltage could be around mV.

To bias a transistor we have to supply datasneet to base datasheft, this current I B should be limited to 5mA by using a transistor to the base pin. 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.

This stage is called Saturation Region. To make this current flow through the transistor the value of base current I B can be calculated using the below formula:
