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 current
source such that the voltage ratings of the devices are exceeded.
