This mosfet can drive loads upto 23A and can support peak current upto A. It also has a threshold voltage of 4V, which means it can easily driven by low voltages like 5V. Hence it is mostly used with Arduino and other microcontrollers for logic switching. Speed control of motors and Light dimmers are also possible with this Mosfet since it has good switching characteristics.
So if you are looking for a Mosfet to switch applications that consume high current with some logic level devices then this Mosfet will be a perfect choice for you. Meaning, they can be turned on or turned off by supplying the required Gate threshold voltage VGS. When a gate voltage is applied these pins gets closed. The below circuit shows how this mosfet behaves when the Gate voltage is applied 5V and not applied 0V.
Since this an N-Channel mosfet the load that has to be switched in this case a motor should always be connected above the drain pin. When you turn on a Mosfet by supplying the required voltage to the gate pin, it will remain on unless you supply 0V to the gate. To avoid this problem we should always use a pull-down resistor R1 , here I have used a value of 10k.
To tackle this we should use a current limiting capacitor, I have a used a value of here.
