ABSTRACT:
The specification discloses a sensitive gate controlled rectifier including a semiconductor body having four layers of alternating opposite conductivity types. A first highly doped region of a first conductivity type is formed in a first exterior layer of the body of the first conductivity type. A second highly doped region of a second conductivity type is formed in the first exterior layer adjacent the first region. A first electrode electrically connects an internal layer of the second conductivity type with the first exterior layer and the first region to form a cathode. A second electrode connects to the second region to form a gate. A third electrode connects to a second exterior layer of the second conductivity type to form an anode.
