1) Supply voltages higher than Vbb(AZ) require an external current limit for the GND and status pins (a 150 resistor in the GND connection is recommended). 2) RI = internal resistance of the load dump test pulse generator 3) VLoad dump is setup without the DUT connected to the generator according to ISO 7637-1 and DIN 40839
