    Hi MonacoFranz,

    The gate capacitance Cge is designed to be large enough to avoid parasitic turn-on effects.
    This negates the need for additional gate capacitors.

    Hi nick,

    I think you mean IGBT7.
    During the overload conditions it is allowed to reach Tj=175C with IGBT7.
    The overload duration where the chip is above 150C must be within 20% of the load...

    Hi Wen,

    Yes. Due to increased gate charge the possibility of parasitic turn on is lower than for IGBT4.
    This makes it suitable for unipolar gate supplies.
    The other benefit of higher Qg is...
