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/s.
5.0 Rate of rise of on-state current
The maximum un-primed rate of rise of on-state current must not exceed 1000A/s at any time during
turn-on on a non-repetitive basis. For repetitive performance, the on-state rate of rise of current must not
exceed 500A/s 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 recommended pulse gate drive is 30V, 30
with a short-circuit current rise time of not more than
0.5s. This gate drive must be applied when using the full di/dt capability of the device.
The pulse duration may need to be configured according to the application but should be no shorter than
20s, otherwise an increase in pulse current may be needed to supply the necessary charge to trigger.
