I am working on project for flyback converter using Ltspice.

Indeed, I have to insert the parameters for MOSFET inside the model but I have faced some difficulties to get the values from datasheet for these parameters:

Rd Drain ohmic resistance.

Rs Source ohmic resistance.

Is Parasitic diode saturation current

Rb Body diode resistance.

Kindly, please can you tell me how to get the values for those parameters from Datasheet. the component I work on it is STW11NM80.

I would appreciate your interest and your help.

Looking forward hearing from your side

Best regards
