As the model for the C3D02060F SiC diode is not available, I decided to venture myself and attempt to build a decent model for Spice. I researched a bit around in the web and found this interesting article about creating your own Spice models for diodes.
Luckily I have the Locky curve tracer and can get the most out of tracing sand devices. I did a quick trace on one of the SiC diodes to capture a good sample set of Vf and If points.
How did I go about to develop the model? Quite simple. I started with ploting the ideal diode response with the Schokley current model. Then I played around with N and Is to fit the curve. Note that this is an iterative manual process, which takes a bit of time but can be done without much difficulty. Finally I created the model in Spice and adjusted Rs by testing manually a pair of Vf/If points. Not perfect, but good enough for what I need:
The graph above has the actual tracer plot (“I”), and both the ideal model (“Schokley model”) as well as the output of LTSpice simulation (“Spice”).
This is a great diode for cathode bias when using drivers which need +15mA at least. If you are interested in the model it can be downloaded from here: C3D02060F model. Hope you find this useful.
