PURPOSE:To form an AC semiconductor switch simplified with a lead frame by electrically connecting a P type gate electrode to an N type gate electrode to pick it up as an auxiliary electrode, thereby reducing the number of steps of connection between the internal electrodes. CONSTITUTION:The cathode of a planar type photosensitive N type gate SCR pellet 33 and the anode electrode of a gate photoSCR pellet are commonly bonded to a common lead 34 to be picked up as a main electrode T2. The cathode electrode of a P type gate SCR pellet 32 and the anode electrode of an N type gate SCR pellet 33 are connected via conductors 20 to lead 36 and are produced as a main electrode T1. The gate electrodes of the pellets 32, 33 are connected via conductors 18 to a lead 35, and are produced as a sole auxiliary electrode G. |
