Reverse load current (through intrinsic drain-source diode) is normally limited by the connected load.

Reverse current I of ≈ 0.3 A at V = -32 V through the logic heats up the device. Time allowed under

GND

these condition is dependent on the size of the heatsink.Reverse I

can be reduced by an additional

GND

external GND-resistor (150 Ω). Input and Status currents have to be limited (see max. ratings page2 and

circuit page 7).
