IGBT AC switch using ADuM3221, what is the effect on the insulation lifetime?

Hi, I am considering using the ADuM3221 to control an 250V AC switch consisting of two series connected IGBTs (collectors together). These IGBTs will be switched at 20kHz this means that the isolation barrier will have a 20kHz 250V square wave across it. Will this device cope with this situation and how will it affect the insulation lifetime?
