Abstract
To provide a semiconductor integrated device capable of a gate screening test with no need for any additional circuit and without adding any gate screening terminal. The semiconductor integrated device includes a gate drive unit configured to drive the gate of a voltage controlled semiconductor element and a regulator configured to supply a gate drive voltage to the gate drive unit. The regulator includes an external connection terminal capable of receiving a gate screening voltage for the voltage controlled semiconductor element in a gate screening test.
