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 Tvj below 25°C.
4.0 Repetitive dv/dt
Standard dv/dt is 1000V/s.
5.0 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.
