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. V and V 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 DRM RRM 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. 2017 Littelfuse, Inc.
