Abstract
A bidirectional semiconductor component having two symmetrical MOS transistor structures integrated laterally in a substrate and connected antiserially, their drain terminals being connected to one another. A zone having the same type of conductivity as the drain region yet a higher doping than that of the drain region is situated upstream from a pn junction of one of the MOS transistors in a junction area with the drain region.
