Stresses exceeding Maximum Ratings may damage the device. Maximum
Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. 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. Blocking
voltages shall not be tested with a constant source such that the voltage
ratings of the devices are exceeded.
