Abstract

PURPOSE:To protect surely an objective IGFET, by providing an IGFET, which has an on-state voltage lower than reverse dielectric strength of the first as well as the second diodes connected between the power source terminal and the earth, to form an electric discharging path. CONSTITUTION:IGFET24, 26 are provided which have on-state voltages lower than reverse dielectric strength of diodes D1 and D2 connected between power source terminal 12 and earth 14, thereby forming an electric discharging path. As a result, objective IGFET16, 20 can be protected surely.
