When using the MOSFET as a switch we can drive the MOSFET to turn "ON" faster or slower , or pass high or low currents . This ability to turn the power MOSFET "ON" and "OFF" allows the device to be used as a very efficient switch with switching speeds much faster than standard bipolar junction transistors.What is the use of MOSFET in electronic circuits?
Some important applications of MOSFET are given below : Mosfet is used for some switching applications an in electronics device. It is used in some amplifying circuits. It is used in chopper circuits MOSFET can be used as a high-frequency amplifier. It can be used in voltage regulator circuits. It is used as an inverter in some of the electronics circuits. It can be used as a passive element e.g. ... More items...How to use MOSFET?
To use a MOSFET as a switch, you have to have its gate voltage (Vgs) higher than the source. If you connect the gate to the source (Vgs=0) it is turned off. For example we have a IRFZ44N which is a “standard” MOSFET and only turns on when Vgs=10V – 20V. But usually we try not to push it too hard so 10V-15V is common for Vgs for this type of MOSFET.How does a MOSFET transistor work?
The MOSFET works by electronically varying the width of a channel along which charge carriers flow (electrons or holes). The charge carriers enter the channel at source and exit via the drain. The width of the channel is controlled by the voltage on an electrode is called gate which is located between source and drain.
