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The curves illustrated in figures 17 & 18 are for guidance only and are superseded by the maximum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 must be taken not to use excessively large values of snubber
capacitor or excessively small values of snubber resistor. Such excessive component values may lead to
device damage due to the large resultant values of snubber discharge current. If required, please consult
the factory for assistance.
7.0 Rate of rise of on-state current
The maximum un-primed rate of rise of on-state current must not exceed 600A/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 300A/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.
