A semi-conductor structure for controlling and switching a current has a switch element and an edge element. The switch element contains a first semi-conductor area of a first conductivity type contacted by way of an anode electrode and a cathode electrode, a depletion area that is arranged inside the first semi-conductor area and that can be influenced by a control voltage applied to the control electrode for the purpose of current control, and an island area of a second conductivity type that is buried inside the first semi-conductor area. The edge element contains an edge area of the second conductivity type that is buried inside the first semi-conductive area and that is formed on a common level with the buried island area, in addition to an edge terminating area of a second conductivity type adjacent the edge area.
