Note 1. Ratings apply for open gate conditions. Devices shall not be tested with a constant current
source for blocking voltage such that the voltage applied 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 is to be used at high sustained currents.
