Working Principle

A MOSFET is an insulated-gate field-effect transistor that utilizes an insulated gate to control the conductivity of a channel between the source and drain. When voltage is applied to the gate, a depletion region is formed in the region between the source and the drain. The width of this depletion region depends on the applied gate voltage; thus by changing the voltage on the gate, MOSFETs can be used to control the flow of current from the source to the drain. STL190N4F7AG operates in the same way. The voltages applied to the gate, source and drain allow for current to flow between the source and the drain. The on resistance (Rdson) of STL190N4F7AG is controlled by the amount of voltage applied to the gate and can be varied from 0.7 to 1 Ohm depending on the operating temperature.
