| Model Description | This physically based
SCR model
provides most of the important device characteristics under static and
dynamic conditions. The model includes turn-on and turn-off
conductivity
modulation effects, accurate reverse recovery waveforms, and the
negative
resistance gate-cathode I-V characteristic. The model is designed using
the lumped-charge methodology.
This model has been available as a commercialized generic model in the Saber simulator with the template name: scr2.sin. |

| Performance Level: | ACCURATE | ||
| Quality Classification: | 3A (Commercial Model)
1A (University Model) Parameter extraction is NOT available. Unlike most of the other models on this set of Web pages, parameter extraction is very difficult as the model was designed without consideration for parameter extraction. |
