In the datasheet for STP36NE06, it has two graphs which seem to contradict each other:
In the graph on the left, for
Id=18A, the slope of the curve indicates that Rds is approximately 0.05 ohms. (Vds would be about 1v). However the graph on the right suggests it would be between 0.6 and 1.8 ohms.
What am I not understanding here?
