    Hi
    Can I connect 4 IGBT devices in parallel to get a larger flow capacity of curent.
    Thanks.

    Great info Wook.

    I didn't consider the importance of sharing a heatsink. Thermal coupling will help keep matched IGBT's at the same temperature during operation so one does not out spec another in temperature dependent characteristics.

    It was a forehead smack, but quite important.

    Thanks again!
