C3D02060F Spice Model

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:CREE C3D02060F Spice Model

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.

  1. Very interesting the SiC diodes for biasing, for me the battery NiMH give the best sound.

    Congratulation for your baby Sofia.

    1. Thank you. Well, the SiC do sound good and provides a good solution for bias current above +15ma. Otherwise, I do like LED bias as well.
      I have to admit that I’ve been implementing filament bias or fixed bias in my latest builds 🙂

      1. Glenn. It’s great to see you motivated back to work on with valves. Am sure you have plenty of experience to share. I’m always keen to learn!! 🙂
        keep me posted on your work
        Ale
