Abstract
PURPOSE: To obtain photo-driving type SCR having large value of dV/dt by building a cathode of photo-driving SCR into large-capacity SCR's gate as a component of one substrate.
CONSTITUTION: Photo-driving SCR 21 and driven SCR 20 are formed in n-type silicon substrate 1 with anode 11' set for common use. The gate 7 of SCR 20 is wire-connected to cathode 8 of SCR 21. If SCR 21 is turned on by light, electric current running through said SCR flows into gate 7, causing SCR 20 to be turned on SCR 21 can be considerably scaled down because it has only to supply gate current to SCR 20. For this reason, the effective area of pn-junction is minimized, resulting in the diminution of the depression layer and an increase in dv/dt caused by a reduction of running current.
