Abstract
PURPOSE: To improve dv/dt, by heightening photosensitivity by exposing more than 3 joints of 6-layer structure composed of pnpnpn.
CONSTITUTION: When light is radiated over to p1n1p2n2, electron-positive hole pairs occur to all the joints J1∼J3 of SCR 1 and to anode-side gate joint J3 of SCR2 and the SCR 1 and the SCR 2 are turned ON at the same time by the reaction. On the other hand, as to dv/dt, as cathode-side gate layer p2n2 of the SCR 2, current amplification factors of n1p2n2 transistor and p2n2p3 transistor become lower extremely and control the reaction, and further, the SCR 1 and the SCR 2 become connected in series, and therefore, the joining capacity Cj becomes small. As a result, dv/dt becomes to have an extremely high resisting capacity. This mechanism makes it possible to obtain a high-capability photothyrister.
