The IGW75N65H5XKSA1 can dissipate 395W & has 0.38 K/W thermal resistance to case (to-247) circuit demands ~500W handling (this is the measured average and with a ~30W margin) surpassing the IGBTs capability and maximum operating temperature. Nominally, for 1 transistor the temp would sky rocket to 215°C from 25°C baseline, question is if I were to gang 2 or more IGBTs would the resultant temperature for each IGBT in the gang simply be the quotient of 215°C and number of parts in gang? Whats a good rule of thumb temperature to keep IGBTs from going into thermal runaway condition?
