Abstract
In an embodiment, a semiconductor device includes: a main bi-directional switch formed on a semiconductor substrate and including first and second gates, a first source electrically connected to a first voltage terminal, a second source electrically connected to a second voltage terminal, and a common drain; and a substrate control circuit. The substrate control circuit includes: a first diode and a second diode; a discharge circuit including a first transistor and a second transistor connected in a common source configuration to the semiconductor substrate; and a gate potential control circuit including a third diode and a fourth diode. The first diode has a forward voltage Vfand the third diode has a forward voltage Vf, where Vf≥1.1Vfor Vf≥1.2Vfor Vf≥1.5Vfor Vf≥2Vf.
