The Ideal Thyristor component models a thyristor with an off-state conductance, $G_{\mathrm{off}}$, and an on-state resistance, $R_{\mathrm{on}}$. The parameter $V_{\mathrm{knee}}$ sets the voltage which commutates the thyristor. If $V_{\mathrm{knee}}<v$, a true value on the Boolean gate input $\mathrm{fire}$ causes the device to go to the on-state. It remains in the on-state, regardless of the value on the gate, until it is commutated (that is, until $v\le V_{\mathrm{knee}}$).

$\mathrm{off}\&equals;\left(s<0\vee \mathrm{pre}\left(\mathrm{off}\right)\wedge \neg \mathrm{fire}\right)$

$i\&equals;i_p\&equals;-i_n\&equals;G_{\mathrm{off}}{V}_{\mathrm{knee}}\&plus;s\{\begin{array}{cc}{G}_{\mathrm{off}}& \mathrm{off}\\ 1& \mathrm{otherwise}\end{array}$

$v\&equals;v_p-v_n\&equals;V_{\mathrm{knee}}\&plus;s\{\begin{array}{cc}1& \mathrm{off}\\ R_{\mathrm{on}}& \mathrm{otherwise}\end{array}$

$\mathrm{LossPower}\&equals;vi$

$T\&equals;\{\begin{array}{cc}{T}_{\mathrm{heatPort}}& \mathrm{Use\; Heat\; Port}\\ 293.15& \mathrm{otherwise}\end{array}$
