Maximum ratings are those values beyond which device damage can occur.
Maximum ratings applied to the device are individual stress limit values (not
normal operating conditions) and are not valid simultaneously. If these limits are
exceeded, device functional operation is not implied, damage may occur and
reliability may be affected.

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.
