Hi,

Got a new project dropped on my desk that is a little out of my knowledge area. Being asked to reverse engineer a circular connector with built-in TVS suppression protection (similar to these: https://www.carlisleit.com/prod-info/tvs-connectors/). Customer's part has been DMS'ed by the original manufacturer so we are designing the replacement so I am speccing out the diodes to use. I was able to determine values for the leakage current and breakdown voltage but I am not sure how to determine the peak pulse power rating (wattage) of the diodes. Is there any way I can determine this without a) running higher pulses into one of the lines until it fails or b) cutting open the connector body and trying to read a part marking on one of the diodes?

Appreciate any direction here. Thanks
