2.0 Extension of Voltage Grades This report is applicable to other and higher voltage grades when supply has been agreed by Sales/Production.
3.0 De-rating Factor A blocking voltage de-rating factor of 0.13%/°C is applicable to this device for Tj below 25°C.
4.0 Repetitive dv/dt Standard dv/dt is 1000V/µs.
5.0 Rate of rise of on-state current The maxim um un-primed rate of r ise of on-state current mus t not ex c eed 400A/µs at any time during turnon on a non-repetitive basis. For repetitive performance, the on-state rate of rise of current must not exceed 200A/µs at any time during turn-on. Note that these values of rate of rise of current apply to the total device current including that from any local snubber network.
6.0 Gate Drive The recomm ended pulse gate drive is 30V, 15Ω with a short-circuit current rise time of not more than
0.5µs. This gate drive must be applied when using the full di/dt capability of the device.
