Ever wondered what the inside of a high-power IGBT module looks like?
Thought this might be interesting to some of you.
This is the inside of a failed Fuji Electric 6MBI75SS-120 IGBT module (1200 V / 75 A).
It’s quite impressive to see the number of aluminum bonding wires used to connect the dies to the power terminals.
The module was already dead, so I decided to open it up rather than throw it away.
