Abstract: According to one embodiment, semiconductor device includes a first terminal, a second terminal, a first transistor, a second transistor, a third transistor, a fourth transistor, and a control circuit. The control circuit is configured to control the first transistor, the second transistor, the third transistor, and the fourth transistor. The control circuit is configured to, when supply of the first voltage to the third node is stopped, turn the second transistor from an off state to an on state, turn the third transistor and the fourth transistor from an on state to an off state, and after a first period passes, turn the first transistor from an off state to an on state.

Abstract: In general, according to one embodiment, a semiconductor device includes a first terminal, a second terminal and a first circuit. The first circuit includes a first switching element, a second switching element and a first resistor. The gate of the first switching element is coupled between the first node and the second terminal. The first resistor and the second switching element are coupled in series between the first node and the second terminal. The first circuit is configured to change the first switching element and the second switching element from an off state to an on state when supply of the first voltage to the first node is stopped.
