Abstract: PURPOSE:To prevent the destruction of elements even when a surge in the negative direction is impressed, by providing a protective diode between an output terminal and a negative power source in a semiconductor integrated circuit device constituting an emitter follower amplifier. CONSTITUTION:A protective diode 20 is connected between an output terminal OUT and a separating layer 17. In this case, the diode 20 is formed with an N-epitaxial layer 22 as the cathode and the P<+> separating layer as the anode on an island (epitaxial layer) 22 independent of an NPN transistor 1. The epitaxial layer 22 as the cathode is connected to the output terminal OUT by an N<+> layer 21.
