NOTE: VDRM and VRRM for all types can be applied on a continuous basis. Ratings apply for zero or negative gate voltage; 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.
