CAB760M12HM3 and CAB530M12BM3 LTSpice Model

Hello Wolfspeed Technicians,

I work in Research and Development and am modelling circuits involving switching devices. Would it be possible to provide any LTSpice models for the models we are most interested in, listed in the following:

CAB760M12HM3

CAB650M17HM3

CAB530M12BM3

This would be a great help,

Thanks

Hi Robert,

I've included preliminary models for the CAB760M12HM3 and CAB530M12BM3 below. However, I have not yet developed the models for the 1.7 kV devices.

To switch between device models, right-click the module block and change the 'Value' field. For example, below is the model changed for the CAB760M12HM3. Here is a list of models included in this library:

CAS175M12BM3,CAS350M12BM3,CAS530M12BM3,CAB530M12BM3,CAB760M12HM3,CAS480M12HM3,CAB400M12XM3,CAB425M12XM3,CAB450M12XM3,CAB016M12FM3

You have a few knobs to turn in the SpiceLine as well. If you set Thermals=0, then the model will use a static temperature defined by the global TEMP variable. By default (Thermals=1) the model uses a closed-loop cauer network. BPC=1 will include the baseplate capacitance for EMI analysis, and the level parameter can be adjusted (1,2,3) to change the complexity/speed of the model (level=1 is the fastest, level=3 is slowest).

Please keep in mind that these models are still being developed and are preliminary. There may be errors in the implementation, and they may not perfectly match dynamic results.

Thanks,

Brian

Thank you!

Took some time to adapt to the model, but this is perfect. Appreciate the help!
