Here lets us assume the 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 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. Top menu About Us Contact.

But this calculation will lead to the closest value to start with. However this vale will not be very accurate because the transistor will have an internal voltage drop across the collector current, n22219 it mostly experimental to get the maximum current from the transistor.
This resistor is connected to the base pin of the transistor to limit the 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.
When this transistor is fully biased then it can allow a maximum of mA to flow across the collector and emitter.
Skip to main content. So to calculate the resistor value of the base we can use the formulae.
But it comes in a metal can package and can operate on voltages slightly higher than what a 2N can handle. To make this current flow through the transistor 2n2219 value of base current I B can be calculated using the below formula:. So the value if R B will be. Current Drains out through emitter, normally connected to ground.

Current flows in through collector, normally 2n219 to load. Overall it is just another small signal transistor which is commonly used in switching and amplifying circuits.
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 2n22119 collector current of mA we have to pass a base current of 16mA. Top menu About Us Advertise.
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. This stage is called Saturation Region.
The value of this current can be calculated by the required amount of current that will be consumed by the load. Next Article Timer IC.
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 22n219 to the data sheet 1.
The 2N is a NPN transistor and is normally used as a switch in many circuits. 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.

Another important thing to keep in 2n2129, while using a transistor as switch is the base resistor. Complete Technical Details can be found at the datasheet given at the end of this page. 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.
