I'm trying to use a N-channel mosfet as a switch. When I have 3.3V on the gate of the mosfet, it lets current flow through the 100 Ohms resistor, but the voltage across the mosfet is above 10mV. The circuit i used is in the attachment. The tested mosfet is the IPP055N03L. It has a max VGS(TH) of 2.2V and a RdsON of around 6.2mOhms.
So my question is: Why is there still 10mV across the mosfet when it should be alot lower? The VGS is above the threshold voltage and the RdsON is so low.
According to the simulation the voltage across the VDS should be 60uV. And according to calculations it should be: 1V/100,0062Ohm*0.0062Ohm = 62uV
