Zener Diode for Simscape.

Hi,

I am trying to get an Zener Diode from Simscape module. I know we can get the Zener Diode from Simulink by typing "power_zener" in command. However, I cannot find any way to connect that zenner to my Simscape-typed circuit. Thank you so much for helping me.

The power_zener uses the Specialized Technology library but, the your model is built using the Simscape library.

To use a diode as zener, change the Reverse breakdown voltage parameter of the diode and specify the Zener resistance. Please see this.

Thank you so much for your help. I change the Reverse breakdown voltage and Zener Resistance following the datasheets of my zener 1N4774A, and I am having the perfect result!

Again, Big Thank!

@Arvind Sathyanarayanan thank you for the detailed answer to this question. What would be nice in a future Simscape version is to have an alternate "Zener" symbol that could be used so it's obvious when looking at the model that it's a zener diode as it would be on a real schematic.

I use Matlab - Simulink - Simscape R2015a. The diode doesn't have the parameter "Reverse breakdown voltage" and "Resistance". How can I simulate a zener diode ?
