1. A set of diodes comprising two diode types for application to alternators, each diode being configured for being connectable between an alternator a-c terminal and a d-c bus heat sink;

  • each said diode comprising;

    a flat thin silicon diode die having first and second main diode electrodes on its opposite respective surfaces, a lead frame having a relatively thick conductive section which receives said first one of said main diode electrodes and which supports said die, and a relatively thin conductive section which is laterally removed from and insulated from said relatively thick section and a wire bond connecting the second one of said main diode electrodes to said relatively thin conductive section, and a plastic insulation housing enclosing said die and at least portions of said relatively thick and relatively thin lead frame sections and said wire bond;

    said relatively thick lead frame section having a bottom which is exposed through said plastic housing for connection to said d-c bus heat sink;

    said relatively thin conductive section defining a connection tab extending through said plastic housing and connectable to said a-c terminal;

    in one of said two diode types, said first and second main diode electrodes being respectively an anode and a cathode of said diode; and

    in the other one of said two diode types, said first and second main diode electrodes being respectively a cathode and an anode of said diode.
