Abstract

A monolithic power switch with a controlled di/dt including the parallel assembly of a MOS or IGBT type component with a thyristor type component, including means for inhibiting the thyristor type component during the closing phase of the switch, which is ensured by the IGBT type component. The IGBT type component has a vertical multicell structure and the component of thyristor type has a vertical monocell structure.
