Negative conduction loss

Hi,

I have problems simulating thermal performance for NTH4L014N120M3P from Onsemi and I am getting the error Negative loss values for component. Can you please hep me figure out what is the error?

This is a numerical issue due to small roundoff errors created by not fully forcing the positive/negative conduction inflection point to be at zero current/zero voltage in the “Conduction Loss (Gate On)” dataset.

To eliminate the error message you can add another entry into the table at 0A with 0V for all temperatures. You can right-click the table select “New current values…” to create this entry and then fill in column with all zeros.
