(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 to be used at high sustained currents.
Preferred devices are recommended choices for future use and best overall value.
