Abstract
An optical coupler has a light-emitting semiconductor component and a light-receiving semiconductor component that are connected to one another via an electrically-insulating, light-transmissive coupling and provide a voltage output, particularly for the drive of field-effect transistors. The light-receiving semiconductor component is a semiconductor chip in which a plurality of photoelements are integrated connected in series.
