I stumble upon some used IGBTs - InfineonFZ600R65KF2. They are used but still in perfect working condition. The units have been swapped for preventative measures. I have about 2000 units

That depends on what you compare with, my Toshiba IGBT (from 1999) has max forward voltage of 3V at 400A 25C.SciroccoEV wrote: ↑Tue Jun 23, 2020 9:15 pm High conduction losses when used at realistic vehicle voltages.
