Claim:
1. A thyristor device, comprising: a semiconductor structure with alternating p-n-p-n layers, the alternating p-n-p-n layers comprising: a cathode electrode located on at least a portion of the upper surface and formed by a first low ohmic resistance metal making ohmic contact with at least the nE layer; an anode electrode located on at least a portion of the lower surface and formed by a second low ohmic resistance metal making ohmic contact at least the pE layer and; a gate electrode formed on at least a portion of the pB layer so as to be disposed over the gate area; and wherein gate current entering the gate electrode flows to at least one particular plural part, which is located between the gate area and the nE layer to charge the alternating p-n-p-n layers and generate an initial turned-on area emanating from each of the at least one particular plural part.
