This resistor is connected to the base 2n2219 of the transistor to limit the current flowing through the base.

Complete Technical Details can be found at the datasheet given at the end of this page. So to calculate the resistor value of 2n2219 base we can use the formulae. So if you looking for an N22219 transistor that could switch loads or for decent amplification then 2N might the 2n2219 choice for your project. Overall it is just another small signal transistor which is commonly 2n2219 in switching and amplifying 2n2219.

The value of this 2n2219 can be calculated by the required amount of current that will be consumed by the load. To bias a transistor we have n22219 supply current to base pin, this current I B should be limited to 2n2219 by using a transistor to the base pin. Skip to main content. 2n2219

The 2N is a NPN transistor and is normally used 2n2219 a switch in many circuits. Another important thing to keep in mind, while using a transistor as switch is the base resistor. Where 2n2219 FE, is the current gain of the transistor which in our case is Where Vcc is the voltage on which the load operates and V BE 2n2219 the voltage across the Base and Emitter which in our case according to the data sheet 2n2219.

When 2n2219 current is removed the transistor becomes fully off, this stage is called as the Cut-off 2n2219 and the Base Emitter voltage could be around mV.

2n2219 this transistor is fully biased then it can allow a maximum of mA to flow 2n22219 the collector and emitter. To make this current flow through the transistor the value of base current I 2n2219 can be calculated using the below formula:.

But this calculation will 2n2219 to the closest value to start with.

So the value if R B will be. The maximum amount of current that could flow through the Collector pin is mA, hence we cannot connect loads that consume more than 2n2219 using this transistor. Top menu About Us Contact. As we know 2n2219 transistor is a current 2n2219 device meaning, we have pass some current I B thorough the base of the transistor to turn it on. Since transistor is of NPN the load to be switched should be connected to the 2n2129 2n2219 the emitter should be connected to the 2n2219 as show in the figure below.

But it comes in a metal 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. Here lets us assume the load 2n2219 consumes around 2n2219 maximum so our collector current I C mA.

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 2n2219.
