Note 1. Ratings apply for zero or negative gate voltage. Devices should not be tested for blocking
capability in a manner such that the voltage applied exceeds the rated blocking voltage.
Note 2. Devices should not be operated with a positive bias applied to the gate concurrently with a
negative potential applied to the anode.
