Sales/Production.

4.0 Repetitive dv/dt
Higher dv/dt selections are available up to 1000V/µs on request.

5.0 De-rating Factor
A blocking voltage de-rating factor of 0.13%/°C is applicable to this device for T

below 25°C.

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 1500A/µs 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 1000A/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 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.

The curves illustrated in figures 10 to 18 are for guidance only and are superseded by the maximum

ratings shown on page 1.

The 100% duty cycle is represented on all the ratings by a straight line. Other duties can be included as

parallel to the first.
