[QUOTE="Shonver, post: 830244, member: 34"] It depends on your application. In linear mode the RDSon figure will have a lesser impact. If you are switching, a low RDSon is desirable, but not the only constraint. To minimise power dissipation in a switching application, it has to switch quickly between hard ON and hard OFF. It is during the transition that it dissipates most of its power, so the switching time has to be as short as possible (again, this is application dependent). [/QUOTE]
