Hello my dear friends, I had made a video on transistor and I got a request to make video about MOSFET. So today we are going to see what is MOSFET , how does it work and where it can be used.
The MOSFET is an abbreviation of Metal Oxide Semi Conductor Field Effect Transistor, so generally it is a Transistor and it has also 3 terminals:
1. Gate
2. Source
3. Drain
Here the voltage given according to the Gate gets increased or decreased through Source to Drain.
Friends MOSFET has also two types:
1. Enhancement Type
2. Depletion Type
In Enhancement type, when Applied Gate Voltage is increased, the current is also increased while in depletion type, when the applied Gate Voltage is increased the amount of current is decreased. Here you can see there is a slight difference between the symbol of both MOSFET. Enhancement type has a dotted-line symbol while depletion type has continuous line symbol. These two symbols show N-channel MOSFET while there is one more type which is called P-channel MOSFET.
Here are the symbols of P-channel type, which is generally depicted by upside-down arrow.
So let's take a look on how to use N-Channel and P-channel type MOSFET in a circuit. In N-channel MOSFET the Source pin in connected to the negative terminal of the battery and the Drain pin is connected through load to the positive terminal of battery. If this is Enhancement type MOSFET, then the load carrying current will be increased after the increase in applied voltage, and if this is depletion type, then the amount of current will be decreased.
While P-channel MOSFET works just the opposite, in this , source is connected to the positive terminal of battery and load is connected between drain and negative terminal of battery. Here also in Enhancement type, when the gate voltage is increased, currwnr through the load is also increased and in depletion type, when voltage is increased, current gets decreased.
So friends, now lets see how to use the most common MOSFET IRFZ44.
IRFZ44 is an N-channel MOSFET and in order to use this, we have to connect source to negative terminal of battery, and load through Drain pin is connected to the positive terminal of battery.
If we connect a variable resistance to battery's negative and positive terminals, and output pin is connected to Gate while voltage is vary so the current through Load is also increased or decreased.
This all can be dony by using Arduino also.
So friends, we have learnt to use MOSFET, now we see why it is used more abundantly,
1. Efficiency: efficiency of MOSFET is very high in comparison with transistors because it consumes very less energy.
2. Easy to manufacture: MOSFETs are very easy to manufacture thus it makes it inexpensive in comparison with transistors.
3. High speed operation: switching of MOSFET at high speed is possible thus it is being used in Radio Frequency circuits too.
Drawbacks of MOSFET:
MOSFETs are very sensitive in comparison with transistors thus due to voltage overload, it leads MOSFET to be damaged easily.
