A high-voltage component and a method for its manufacture. The component functions to switch currents at high voltages. The component is composed of partial components that are connected in series and are laterally supported on a self-supporting semiconductor wafer. The partial components switch through, for example, at a given voltage applied between a first bridge cathode and an anodic metallization.

High voltage component and method for making same

A break-over photodiode, designed as a light-sensitive thyristor, can be stacked using a series connection with a plurality of break-over photodiodes, such stacking representing a high-voltage break-over diode. The break-over photodiode can be triggered by lateral illumination in an edge zone, and includes a gate-layer resistivity under the emitter which is greater in an edge zone of the break-over photodiode than in the central zone of the break-over photodiode. The light sensitivity of the laterally illuminatable break-over photodiode is increased by a greater gate-layer resistivity in the edge zone as compared to the central zone.
