04 400 500 260
06 600 700 420
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 Snubber Components
When selecting snubber components, care m ust be taken not to use ex cessively large values of snubber
capacitor or excessively sm all values of snubber re sistor. Such exc essive com ponent values may lead to
device damage due to the large resultant values of snubber disc harge current. If r equired, please consult
the factory for assistance.
