The IGBT of my induction cooker recently blown up and I have found it's FGA20S125P which is a 1250V 20A Shorted anode type IGBT. The datasheet is available here. However I couldn't find this IGBT model and overseas orders would take months to reach me at a reasonable cost.
I came across a different IGBT Called IRG4PH50UD which has almost same parameters (close enough I guess) from a local vendor. The datasheet is available here.
However this IGBT is mentioned as an "UltraFast CoPack IGBT" with a weird symbol as shown below.
I couldn't find much information what "Copack IGBT" means. It seems to be some kind of small improvement to existing IGBT technology. Could someone explain me what this term means? Would I be possibly able to replace FGA20S125P with this IGBT? The datasheet parameters looks almost similar as far as my knowledge on IGBTs goes. Also please note that I have limited experience using IGBTs as well.
