I’m trying to create the loss model of a MOSFET power module and would like to use the MOSFET-with-diode component from the PLECS library instead of using a separate MOSFET and a diode.

I found a way to input the diode and MOSFET conduction loss data into separate tabs by enabling gate dependent conduction losses (which is not intuitive to discover, by the way), but I can’t find a way to enter the reverse recovery losses of the body diode.

There are tabs to enter the turn-on and off losses of the MOSFET, but nothing to enter the reverse recovery losses of the body diode. Is there a way to do this?

> as per the below screenshot of the PLECS User Manual on this topic, you can enter the body diode Err losses in the left half plane (negative currents) of the Turn-off losses table:
