BIDIRECTIONAL POWER SWITCH

摘要

A switch includes three components. Each component includes a stack of three semiconductor regions of alternating conductivity types and a control region in a first of the three semiconductor regions having a type opposite to that of the first semiconductor region. The first semiconductor regions of the first and second components are of a same conductivity type and the first semiconductor regions of the first and third components are of opposite conductivity types. The first semiconductor region of the first component is connected to the control regions of the second and third components. The first semiconductor regions of the second and third components are connected to a first switch terminal, the third semiconductor regions of the first, second, and third components are connected to a second switch terminal, and the control region of the first component is connected to a third switch terminal.
