Abstract: A one-direction conduction device includes a first transistor and a driving circuit. The first transistor has a control terminal coupled to a first node, and input and output terminals respectively coupled to input and output electrode terminals of the one-direction conduction device. In the driving circuit, a switch circuit is coupled to the input electrode terminal and a second node. A second transistor has a base and a collector both coupled to a third node, and an emitter coupled to the second node. A first resistor is coupled to the third node and ground. A third transistor has a base coupled to the third node, an emitter coupled to the output electrode terminal, and a collector coupled to the first node. The second resistor is coupled between the first node and the ground. The switch circuit breaks off a reverse leakage current path of the one-direction conduction device.
