First. Read the instructions for thyristors and remember which parameters are mentioned. Second. I offered the model from St. in vain. The model lacks many parameters. Therefore, let’s not discuss it. Vdrm => Forward breakover voltage
Vrrm => Reverse breakdown voltage
Idrm => Peak blocking current
Ih => Holding current
dVdt => Critical value for dV/dt triggering
Igt => Gate trigger current
Vgt => Gate trigger voltage
Vtm => On-state voltage
Itm => On-state current
Ton => Turn-on time
Toff => Turn-off time
About the discrepancy between the names in the symbol and in the model. They may not match. The main thing is that the sequence must be followed.
