I want to simulate this component which has a particularly low gate threshold so I want the model to be the right one.
This comes from Diodes Inc DMN5L06DWK.
MS seems to have problems with the .model DSUB CJO parameter and claims it results in a negative value.
I just deleted the CJO parameter and it works. I haven't been able to find a reference to help me understand this syntax.
Here is the model as provided and with the problem line commented and fixed to run.
Can anyone explain what the deal is with the DSUB model and the CJO parameter?
Thanks.
