In MOSFET datasheets they often lists parameters like VGS (ON) , Id (ON). Is VGS (ON) is the testing gate- source voltage that is being used (of course above threshold voltage) or it's a particular constant gate-source voltage which turns the MOSFET FULLY TURN ON? similarly what is this on state drain current?
As far as I know the degree of "on-ness" depends on the gate voltage, so what does it mean to have a "on" state drain current Id on? It is meaningless because the degree of "on-ness" depends on the user hence, different degree means different drain current. So, is on state drain current is the saturation drain current for a testing gate voltage?
