Notes
a. Not to exceed TPULSE = 50 ns.
b. Requires a 150-W resistor in GND connection. The reverse load current through the intrinsic drain-source diode has to be limited by the connected load. Pow-
er 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 Maximum Ratings, page 2.)
