Hi,
I tried to simulate zener diode BZT52C4V7 or another but diodes did not work correct - output voltage was not 4.7 volts. Only BZt52C10 worked correct (this zener diode is at menu among diodes) - output voltage was correct. What can I do for correct simulation?
Thanks,
Karel
Brand new interactions and interfaces. 
Easy to use and quick to get started. 
The following 4.7V zener device models are currently available in EasyEDA:
You just need to place the BZT52C10 symbol from the EasyEDA Libs and then change the name shown in the schematic to the new model and then, with the symbol still selected, type
Iand set theSpice prefixtoDfor a .model defined model orXfor a .subckt defined model.Please see this post to see how to find and use them.:

You can also copy and paste your own model directly into your schematic as described in the relevant section of the EasyEDA Simulation eBook, referenced in the above post.
