ringing. If the pulse voltage is lower than the rated DC voltage, the rated voltage pulse slope may be multiplied by U
divided by the applied voltage.
For all other pulses following equation must be fulfilled:
T is the pulse duration.
The rated voltage pulse slope is valid for ambient temperatures up to 85 °C. For higher temperatures a derating factor of 3 %
per K shall be applied.
