摘要：
A semiconductor switching device includes first to fourth layers, a first gate portion, a second gate portion and a common gate terminal interconnecting the first and second gate portions. The first gate portion is the current control type and has a rectifying PN junction, and the second gate portion is the voltage control type. When a first polarity vias voltage is applied to the common gate terminal, the device turns on through the second gate portion, while turns off through the first gate portion when a second polarity vias voltage is applied to the terminal.
