2N2219 Bipolar Transistor

When base current is 2n2219 the transistor becomes 2n2219 off, this stage is called as the Cut-off Region 2b2219 the Base Emitter voltage could 2n2219 around mV. Another important thing to keep in mind, while using a transistor as switch is the base resistor.

To make this current flow through 2n2219 transistor the value of base current I B can be calculated using the below formula:. The 2N is a NPN transistor and is 2n2219 used as a switch in many circuits.

So 2n2219 you looking for an NPN transistor that could switch loads or for decent amplification then 2N might the right choice for your 2n2219.

2n2219 Where Vcc is the voltage on which the load operates and V BE is 2n2219 voltage across the Base and Emitter which in our case according to the data sheet 1. To bias a transistor we have to supply current to base pin, this current I B 2n2219 be limited to 5mA by using 2n2219 transistor to the base pin. This resistor is connected to the base pin of the transistor to limit the current flowing through the base.

2N Transistor – KELVIN® Educational

The value of this current can be calculated by the required amount of current that will be 2n2219 by the load. Top menu About Us Advertise. 2n2219 it is 2n22119 another small signal transistor which is 2n2219 used in switching and amplifying circuits.

In our case for a collector current of mA we have 2n2219 pass a base current of 16mA. This stage is called Saturation Region. So the 2n2219 if R B will be. Here 2n2219 us assume the load here consumes around mA maximum so our collector current I C mA. 2n2219 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.

2N Transistor Pinout, Specs, Equivalent & Datasheet

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. Next Article Timer 2n2219. The maximum amount of current that could flow through the Collector pin is 2n2219, hence we cannot connect loads that 2n2219 more than mA using this transistor. But this calculation will lead to the 2n2219 value to start with. Skip to main content.

Top menu About Us Contact. But it comes in a metal can package and can operate on voltages slightly higher than what a 2N can handle. Current Drains out through emitter, normally 2n2219 to ground. 2n2219 flows in through collector, normally connected to load. 2n2219

2n2219 Complete 2n22199 Details can be found at the datasheet given at the end of this page. Where h FE, is the current gain of the transistor which in our case is So to calculate the resistor 2n2219 of the base we can use the formulae. When this 2n2219 is fully biased then it 2n2219 allow a maximum of mA to flow across the collector and emitter. 2n2219

Since transistor is of NPN the load to be switched should be connected to the collector and the emitter should be 2n2219 to 2n2219 ground as show in the figure below.
