Claim 1
Independent Claim
123 words
A CONTROLLED POWER RECTIFIER COMPRISING A SILICON SEMICONDUCTOR HAVING P, N AND P LAYERS, AN ANODE TERMINAL ON ONE SIDE, A CATHODE TERMINAL LEAD AND A GATE TERMINAL LEAD ON THE OTHER SIDE, A DIFFUSES N LAYER ON THE CATHODE SIDE COVERING A SUBSTANTIAL PORTION LESS THAN ALL OF THE P LAYER SURFACE, METAL PLATING FOR SOLDERING OF THE CATHODE TERMINAL LEAD ON THE N SURFACE PORTION, METAL PLATING FOR SOLDERING OF THE GATE ON THE P SURFACE PORTION, THERE BEING A GAP IN THE METAL PLATING BETWEEN THE SAID N AND P SURFACE PORTIONS, THE PLATING AT ONE POINT OF LIMITED AREA BEING CARRIED OVER THE SAID GAP FROM ONE PORTION TO THE OTHER PROVIDING A RESISTIVE CONNECTION BETWEEN THE TWO PORTIONS.
