TʻO nā hiʻohiʻona maikaʻi a maikaʻi ʻole o ka thyristor bidirectional he symmetrical, a hiki ke alakaʻi ʻia i kēlā me kēia ʻaoʻao, no laila he mea hoʻololi AC kūpono.

ʻO ka thyristor bidirectional, e like me ka unidirectional thyristor, loaʻa nā hiʻohiʻona mana o ka trigger, akā aia kahi ʻokoʻa nui.ʻAʻole pili i ke ʻano o ka volta polarity i hoʻopili ʻia ma waena o ka anode a me ka cathode, ʻoiai ke hoʻohui ʻia ka pulse trigger i kāna electrode mana me ka nānā ʻole i ka polarity o ka volta, hiki ke alakaʻi pololei ʻia ka thyristor bidirectional.A no kēia mea, ʻaʻohe ʻokoʻa ma waena o ka anode a me ka cathode o nā electrodes nui ʻelua o ka thyristor bidirectional.A ʻaʻohe mea ʻokoʻa ma waena o ka volta kiʻekiʻe maikaʻi a me ka volta kiʻekiʻe hope akā hoʻokahi wale nō volta kiʻekiʻe loa.ʻO nā ʻāpana ʻē aʻe o ka thyristor bidirectional e like me ka unidirectional thyristor.ʻO ka maʻamau o ka electrode nui i pili i ka mea semiconductor P-type i kapa ʻia ʻo ka T1 electrode, a ʻo ka electrode i hoʻopili ʻia i ka mea semiconductor N-type i kapa ʻia ʻo T2 electrode.A ʻo nā electrodes nui ʻelua o ka thyristor bidirectional ʻaʻohe ʻokoʻa ma waena o ka maikaʻi a me ka maikaʻi ʻole.
