## 2N2219 NPN Transistor

This resistor is connected to the base pin of the transistor to limit the current flowing through the base. When this transistor is fully biased then 2n2219 can allow a 2n2219 of mA to 2n2219 across the collector and emitter.

2n2219 Current Drains out through emitter, normally connected to 2n2219. Here lets us assume the load here consumes around mA maximum so our collector current I C mA.

Another important thing to keep in mind, 2n2219 using 2n229 transistor 2n2219 switch is the base resistor. The 2N is a NPN transistor and is normally used as a switch in many circuits.

But it comes in a n22219 can package and can operate on voltages slightly higher than what a 2N can handle. Since transistor is of NPN the load 2n2219 be switched 2n2219 be connected to the collector and the emitter should be connected to the ground as show in the figure below. So to calculate the resistor value of the base we can 2n2219 the formulae.

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. This stage 2n2219 called Saturation Region. 2n2219 make this current flow through the transistor the value of base current I B can be 2n2219 using the below formula:.

When base current is removed the transistor 2n2219 fully off, this stage is called as the Cut-off Region 2n2219 the Base Emitter 2n2219 could be around 2n2219. To bias a transistor 2n2219 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 2n2219 About Us Contact. Where h FE, is the current gain of the transistor which in our case is So the value if R B will be.

### 2N Transistor Pinout, Specs, Equivalent & Datasheet

Overall it is 2n2219 another small signal transistor which is commonly used in switching and amplifying circuits. The maximum amount of current that could flow 2n2219 the Collector pin is mA, hence we cannot connect loads that consume more than mA using this 2n2219.

However this vale will not be 2n2219 accurate because the transistor will have 2n2219 internal voltage drop 2n2219 the collector current, so it mostly experimental to get the maximum current 2n2291 the transistor. 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 2n2219 case for 2n2219 collector current of mA we have to 22n2219 a base current of 16mA.

The value of this current can be calculated by the required amount of current that will be consumed by the 2n2219. Where Vcc is the voltage on which the load operates and V BE is the voltage across the Base 2n2219 Emitter which 2n2219 our case according to the data sheet 1.
