Abstract: The present disclosure provides a nitride-based bidirectional switching device with substrate potential management capability. The device has a control node, a first power/load node, a second power/load node and a main substrate, and comprises: a nitride-based bilateral transistor and a substrate potential management circuit configured for managing a potential of the main substrate. By implementing the substrate potential management circuit, the substrate potential can be stabilized to a lower one of the potentials of the first source/drain and the second source/drain of the bilateral transistor no matter in which directions the bidirectional switching device is operated. Therefore, the bilateral transistor can be operated with a stable substrate potential for conducting current in both directions.
