PURPOSE:To allow the internal connection and the external terminal leadout of a semiconductor by a single body and thus improve the workability by a method wherein external lead-out terminals is formed by bending one side of the opposite side of a peripheral frame vertically to a plane of extended projection, and separating it corresponding to the projection. CONSTITUTION:Since top ends of a cathode electrode 13 and an anode electrode 16 are on the same plane, the top ends are inserted into holes of terminals 24, 25, 27, 28, 29 and 32 of the connection conductor and can be brazed. The substrate 11 of a thyristor element is fixed on a bottom plate 42 of the vessel via an insulation plate 41, and, in the vessel constituted of the bottom plate 42 and a side wall 43, resin 44 is cast so as to bury the thyristor element. The projection (external lead-out terminal) 23 out of the resin 44 is further bent again at a right angle along the lid body 45 of the vessel, and is used for connection to the external conductor, together with a nut 46 dropped in the recess of the lid body 45. It is effective to provide a cut 33 on the external lead-out terminal 23 in a transverse direction. The cut 33 shows an effect to the compression and tensile stress due to the external stress. |
