f = 1kHz, Note 3
Note 1. All gated breakdown voltages are measured while the device is conducting rated gate cur-
rent. This insures that the gate voltage limiting network is functioning properly.
Note 2. Pulse Test: Pulse Width = 30µs, Duty Cycle 2%.
Note 3. This parameter must be measured with bias voltages applied for less than five (5) seconds
to avoid overheating.
