1. VDRM and VRRM for all types can be applied on a continuous basis. Ratings apply for zero or negative gate voltage; however,
(cont.)
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.
