Abstract

PURPOSE:To improve dv/dt characteristics by providing projections extruded from P1 and P2 layers at the N1 layer around the border of both conductive pathes for a TRIAC having the P2-N1-P1-N3 layers of the conductive path faced in opposite to the P1-N1-P2-N2 layers of the conductive path running from the first electrode to the second electrode in the same substrate. CONSTITUTION:Projection sections 16, 17 extruded from a P1 layer and a P2 layer are formed on a common base N1 layer, wherein the projection sections are formed on approx. border between the right side and the left side of conductive regions of a TRIAC. Therefore, when the right side region is conducted, the holes in a base layer 2a which belongs to the N1 layer is swept if the voltage is changed to reverse voltage. And the projections 16 and 17 prevent the holes from flowing into the base layer 1b of the left side conductive path. Therefore, the characteristics of dv/dt will be heightened.
