Hi guys,

I want to know where I can get the PSpice model for any of these MOSFET of 650V SiC Trench family:

  • IMZA65R027M1H
  • IMZA65R048M1H
  • IMZA65R072M1H
  • IMZA65R107M1H


I use this library:
https://www.infineon.com/dgdl/Infineon-CoolSiC_silicon_carbide_MOSFET_650V_SPICE-SimulationModels-v0...

I had to do a few tweaks to make it work, however, in the end, I am stuck with this error:
ERROR(ORPSIM-15167): Undefined parameter: LN.

which refers to this line:
.FUNC VGEff(T,VD,VG) = {(VGS(T,VD,VG) + LN(2*cosh(VGS(T,VD,VG))))/2 + 0.0001}

(writing ln in lowercase does not solve it)

I would appreciate it if you can help me solve this problem or find a proper PSpice model.

Best regards,
Afshin

Hi,

The PSpice model for 650V CoolSiC Trench MOSFET can be downloaded from the following link,

https://www.infineon.com/cms/en/product/power/mosfet/silicon-carbide/discretes/imza65r027m1h/#!simul...

The simulation models has 3 libraries, L0, L1 and L3. The difference between these 3 models can be understood from the following document,

https://www.infineon.com/dgdl/Infineon-ApplicationNote_PowerMOSFET_SimulationModels-AN-v01_00-EN.pdf...

I used L0 model in SIMetrix simulation and it worked fine for me. There was no error after the simulation. Please let me know the model that you have used for your simulation circuit.
