Abstract
An object is to provide a technique capable of suppressing heat occurring in a second semiconductor switching element. A semiconductor device includes a parallel circuit in which a first semiconductor switching element and a second semiconductor switching element are parallelly connected and a gate drive circuit. When a state continuing time which is a time during which the state of the input signal continues is equal to or larger than a threshold value, the gate drive circuit turns off the second semiconductor switching element while keeping ON of the first semiconductor switching element, or reduces a power conduction capability of the second semiconductor switching element while keeping ON of the first semiconductor switching element.
