Diode forward drop of PLECs model doesn't match datasheet

Zan_H

Does your PLECS device model data represent typical values? Comparing the forward drop to the datasheet for C3M0060065K.xml and the model value is higher than the typical value that I see in the DS.

Hi Zan,

The way we extract the forward voltage of the body diode may result in some variance between the typical value listed in the datasheet versus the actual value that is seen in the particular part that was used to create the model. This electrical parameter is known as the vf_body_diode parameter in our component library and you can change it to match whichever scenario you would like (like the max of 5.1V or 4.8v, etc). If you're implementing this as a single diode component (not using out library) then you can just adjust the Forward Voltage parameter to match.

Thanks,

Zack

Hi Zack,

One thing that we noticed is that Turn off switching loss decreases between 13.25A and 22.52A in the model. Is that accurate? I did notice that the Eoff curve of C3M0060065K in that region is very flat however it should probably still increase with current?

Thanks,

Zan
