2.0 Extension of Voltage Grades This report is applicable to other 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5.0 Frequency Ratings The curves illustrated in figures 17 & 18 are for guidance only and are superseded by the maximum
ratings shown on page 1. For operation above line frequency, please consult the factory for assistance.
6.0 Snubber Components When selecting snubber components, care m ust be taken not to use ex cessively large values of snubber
capacitor or excessively sm all values of snubber re sistor. Such exc essive com ponent values may lead to
device damage due to the large resultant values of snubber disc harge current. If r equired, please consult
the factory for assistance.
7.0 Rate of rise of on-state current The maxim um un-primed rate of rise of on-s tate current must not exceed 1000A/µs at any time during
turn-on on a non-repetitive basis. For repetitive per formanc e, the on-state rate of rise of curr ent mus t not
exceed 500A/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.
8.0 Square wave frequency ratings These ratings are given for load component rate of rise of on-state current of 50A/µs.
9.0 Duty cycle lines The 100% duty cycle is represented on the frequency ratings by a straight line. Other duties can be
included as parallel to the first.

10.0 Gate Drive The nominal requirement for a typical gate drive is illustrated below. An open circuit voltage of at least 30V
is assumed. This gate drive must be applied when using the full di/dt capability of the device.
