The on-state resistance
temperature
The on-state resistance in reverse polarity mode is described in
Figure 6
At small load currents the resistance is artificially increased to improve current sense
accuracy. Therefore the forward voltage drop
proportional to the load current
to remain clamped to a defined value
typical device.
