Abstract
PURPOSE: To improve switching speed and protect from break caused by sudden large current and improve reliability by applying light to a plurality of point at the same time by respective photo trigger signal divided into a plurality.
CONSTITUTION: P-layer 2, N-layer 3, P-layer 5 and N+-layer 5 are stacked and electrodes 6, 7 are attached to the layers 2, 5. A plurality of through hole 8 are mounted on the electrode 7 and a branch 10 of a photofiber 9 is inserted therein. Photo trigger signal divided by the branch into plurality is supplied to the surface of the n+-layer 5 of SCR element at the same time. Accordingly, immeadiately after are energizing current extend in transverse direction at applying part at the same time and extend to whole areas in very short time. Further, when great current is suddely flows, flowing passage becomes plural and so partial temerature raising does not occur and partial heating of the element by photo energy of photo trigger signal does not generate and a device having high reliability is obtained.
