Output On-state Resistance
The on-state resistance depends on the junction temperature TJ and on the applied input voltage. Figure 9
show this dependencies in terms of temperature and voltage for the typical on-state resistance RDS(ON). The
behavior in reverse polarity is described in“Reverse Current capability” on Page 13
