1.

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.

2.

Rating is for tw = 1ms.

3.

Test conditions: IG = 150mA, VD = Rated VDRM, ITM = Rated value, TJ = 125°C.
