(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.
These devices are rated for use in applications subject to high surge
conditions. Care must be taken to insure proper heat sinking when the device
is to be used at high sustained currents.
