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 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.

Otherwise, an increase in pulse current could be needed to supply the necessary charge to trigger. The ‘back-porch’ current I magnitude in the order of 1.5 times I
should remain flowing for the same duration as the anode current and have a

.

6.0 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The curves illustrated in figures 17 & 18 are for guidance only and are superseded by the maximum ratings shown on page 1.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.

7.0 Rate of rise of on-state current

The maximum un-primed rate of rise of on-state current must not exceed 300A/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 150A/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.

10.0 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.
