    Body Diode

    Do CoolSiC MOSFETs have a body diode?

    Yes, all CoolSiCTM MOSFET devices packaged in Infineon modules or Infineon’s discrete portfolio have a body diode integrated, which is released for operation. An additional Schottky diode is not required.

    Hi Melli,

    for thermal design you should consider that this body is only conduction during deadtime. Hence the high forward voltage is no big issue. In a typical halfbridge configuration with standard gate signals, the will be conduction of the channel most of the time (synchronous rectification).

    Best regards,
    The views expressed here are my personal opinions, have not been reviewed or authorized by Infineon and do not necessarily represent the views of Infineon.
