Abstract
A semiconductor device according to an embodiment comprises a first transistor capable of supplying or interrupting power to a load. A clamper comprises a first clamping part and a second clamping part connected in series between one end of the first transistor and a gate of the first transistor and becomes a conduction state when a voltage of the one end of the first transistor exceeds a predetermined voltage. A clamp operation detector is provided between the first clamping part and the second clamping part. A second transistor is connected in parallel with the second clamping part. A delay circuit is provided between the clamp operation detector and a gate of the second transistor.
