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 Extension of Turn-off Time

sales/production.

4.0 Repetitive dv/dt

Higher dv/dt selections are available up to 1000V/us on request

5.0 De-rating Factor

A blocking voltage de-rating factor of 0.13%/

6. 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 components values

may lead to device damage due to the large resultant values of snubber discharge current. If required,

please consult the factory for assistance
