Device on 50 mm × 50 mm × 1.5 mm epoxy PCB FR4 with 6 cm2 (one layer, 70 µm thick) copper area for
drain connection. PCB is vertical without blown air.
Not subject to production test, specified by design
VLoadDump is set up without the DUT connected to the generator per ISO 7637-1 and DIN 40839. Supply
voltages higher than Vbb(AZ) require an external current limit for the GND pin, e.g. with a 150 Ω resistor in
GND connection. A resistor for the protection of the input is integrated.

Requires a 150 Ω resistor in GND connection. The reverse load current through the intrinsic drain-source
diode has to be limited by the connected load. Power dissipation is higher compared to normal operating
conditions due to the voltage drop across the drain-source diode. The temperature protection is not active
during reverse current operation! Input current has to be limited (see Absolute maximum ratings on page
6).
