Note 1. VRRM can be applied on a continuous DC basis without incurring damage. Ratings apply
for zero or negative voltage. Device should be tested for blocking capability in a manner such
that the voltage supplied exceeds the rated blocking voltage.
Note 2. This device is rated for use in applications subject to high surge conditions. Care must be
taken to insure proper heat sinking when the device i to be used at high sustained currents.
