For Thyristor  models, please see Thyristor / SCR and: BT151\_500R\_EE Thyristor test jig in: [https://easyeda.com/example/project-BDxrlDVdv](https://easyeda.com/example/project-BDxrlDVdv) (There is also a Triac model in this collection) and: [https://easyeda\.com/andyfierman/Thyristor\_dv\_dt\_demo\-DFztL3Xfx](https://easyeda.com/andyfierman/Thyristor_dv_dt_demo-DFztL3Xfx) If you go to ST.com and search for: Diacs PSpice model (.lib) you will be able to download a Pspice library that will run in LTspice on EasyEDA. To find out how to use the subcircuits in this library, please see (3) in (2) in: [https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a](https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a)

Ignore the message about missing models: it's a bug: [https://easyeda.com/forum/topic/SIM-mode-incorrectly-reports-missing-models-when-they-are-already-in-the-library-873f3fb330e74b08bec474810fe98987](https://easyeda.com/forum/topic/SIM-mode-incorrectly-reports-missing-models-when-they-are-already-in-the-library-873f3fb330e74b08bec474810fe98987)
