Storage temperature range Mounting torque 1. 2. 3. The rated voltage can be applied over the rated operating junction temperatures without incurring damage. Ratings apply for shorted-open or shorted-gate conditions or negative voltage on the gate. Devices should not be tested for blocking capability in a manner such that the voltage supplied exceeds the rated blocking voltages. Rating is for tw = 1ms. Test conditions: IG = 150mA, VD = Rated VDRM, ITM = Rated value, TJ = 125°C.
