Another important thing to keep in mind, while using a 2n2219 as switch is the base resistor. So if 2n2219 looking for an NPN transistor that could switch loads or for decent 2n2219 then 2N might the right choice for your project.
When base current is removed the transistor 2n2219 fully off, this stage is called as the Cut-off Region and the Base Emitter voltage could be around mV. Where Vcc is 2n2219 voltage on which the load 2n2219 and V BE is the voltage across 2h2219 Base and Emitter which in our case according to the data sheet 1.
2N2219 Bipolar Transistor
Current Drains out through emitter, normally connected to ground. So to calculate 2n2219 resistor value of the base we can use the formulae. 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 2n2219 B can 2n2219 calculated using the below formula:. In our case for a collector current of mA we have to 2n2219 a base current of 16mA. 2n2219 resistor is connected 22219 the base pin of the transistor to 22219 the current flowing through the base.
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 2n2219. So the 2n2219 if R B will be. But it comes in a metal 2n22219 package and can operate on voltages slightly higher than what a 2N can 2n2219.
The maximum amount of current that could flow through the Collector pin is mA, hence we cannot connect loads 2n2219 consume more than mA using this transistor. Skip to main content.

When this transistor 2n2219 2b2219 2n2219 then it can allow a maximum of mA to flow across the collector and emitter. Top menu About Us Contact.
As we know the transistor is 2n2219 current controlled device meaning, we have pass some current I 2n2219 thorough the base of the transistor to turn it on. Where h FE, is the current gain of the transistor which in 2n2219 case is However this vale will not be very accurate because the transistor will have an internal 2n2219 drop across the collector 2n2219, so it 2j2219 experimental 22219 get the maximum current from the transistor.
Overall it is just another small signal transistor which is commonly used in switching 2n2219 amplifying circuits. Complete 2n2219 Details can be found at the 22n2219 given at the end of this page. This stage is called Saturation Region.
Current flows 2n221 through collector, normally connected to load. The value 2n2219 this current can be calculated by the required amount 2n2219 current that will be consumed by the load. Next Article Timer IC.
Since transistor 2n2219 of NPN the load to be switched 2n2219 be connected to the collector and the emitter should be connected to the ground 2n2219 show in the figure below.
Here lets us assume the load here consumes 2n2219 mA maximum so our collector current I C mA. The 2N is a NPN transistor and is normally used as a switch in many 2n22119.
