Tizici ezinhle nezingezinhle ze-thyristor ye-bidirectional i-symmetrical, futhi ingenziwa kunoma iyiphi indawo, ngakho iyidivayisi ekahle yokushintsha i-AC.

I-thyristor ye-bidirectional, ifana ne-thyristor unidirectional, inezici zokulawula i-trigger, kodwa kunomehluko omkhulu.Kungakhathaliseki ukuthi iyiphi i-polarity voltage exhunywe phakathi kwe-anode ne-cathode, inqobo nje uma i-trigger pulse yengezwa ku-electrode yayo yokulawula kungakhathaliseki ukuthi i-polarity ye-voltage, i-thyristor ye-bidirectional ingenziwa ngokuqondile.Futhi kulokhu kusho ukuthi akukho mehluko phakathi kwe-anode ne-cathode yama-electrode amabili ayinhloko we-bidirectional thyristor.Futhi awukho umehluko phakathi kwe-voltage ephezulu ephezulu kanye ne-voltage ephezulu ehlehlayo kodwa kuphela i-voltage eyodwa ephezulu ephezulu.Eminye imingcele ye-thyristor ye-bidirectional iyafana ne-thyristor unidirectional.Ngokuvamile i-electrode eyinhloko exhunywe ku-P-type semiconductor material ibizwa ngokuthi i-electrode ye-T1, kanti i-electrode exhunywe ku-N-type semiconductor material ibizwa ngokuthi i-T2 electrode.Futhi ama-electrode amabili ayinhloko we-bidirectional thyristor awanawo umehluko phakathi kokuhle nokubi.
