A bidirectional switching device and applications thereof

Abstract

The application discloses a bidirectional switch device and application thereof. The device comprises a substrate, a channel layer formed on the substrate, a barrier layer formed on the channel layer, a first electrode and a second electrode formed on the channel layer and located on both sides of the barrier layer, a first gate and a second gate formed on the barrier layer and arranged at intervals between the first electrode and the second electrode, a first switch tube formed by electrically connecting the first electrode, the first gate and the second electrode, a second switch tube formed by electrically connecting the first electrode, the second gate and the second electrode, the first switch tube is controlled to be turned on or turned off by applying a voltage signal to the first gate, and a current is formed from the second electrode to the first electrode when the first switch tube is turned on, the second switch tube is controlled to be turned on or turned off by applying a voltage signal to the second gate, and a current is formed from the first electrode to the second electrode when the second switch tube is turned on. The application can realize the function of bidirectional switch in the same chip device.
