Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. **1.** VDRM and VRRM for all types can be applied on a continuous basis. Ratings apply for zero or negative gate voltage; however, positive gate voltage shall not be applied concurrent with negative potential on the anode.
