    摘要: A thyristor device includes a semiconductor body and a conductive anode. The semiconductor body has a plurality of doped layers forming a plurality of dopant junctions and includes an optical thyristor, a first amplifying thyristor, and a switching thyristor. The conductive anode is disposed on a first side of the semiconductor body. The optical thyristor is configured to receive incident radiation to generate a first electric current, and the first amplifying thyristor is configured to increase the first electric current from the optical thyristor to at least a threshold current. The switching thyristor switches to the conducting state in order to conduct a second electric current from the anode and through the semiconductor body.
