Abstract
A semiconductor device includes a semiconductor layer, an insulation gate-type first transistor which is formed in the semiconductor layer, an insulation gate-type second transistor which is formed in the semiconductor layer, and a control wiring which is formed on the semiconductor layer such as to be electrically connected to the first transistor and the second transistor, and transmits control signals that control the first transistor and the second transistor to be in ON states in a normal operation and that control the first transistor to be in an OFF state and the second transistor to be in an ON state in an active clamp operation.
