Abstract: A photocoupler comprises an input side lead frame; an output side lead frame disposed facing the input side lead frame with a gap therebetween; a light emitting device mounted on a face of the input side lead frame facing the output side lead frame side; a light receiving device mounted on a face of the output side lead frame facing the input side lead frame side, opposite to and having a gap with the light emitting device; and a protrusion disposed on at least a part of an area around the light receiving device on the output side lead frame and being formed of conductive bonding wire or a bump, protruding to the input side lead frame side.

Abstract: A semiconductor device includes a first nonlinear element, an differential amplifier that generates a differential signal from a signal output by the first nonlinear element; a first and second insulating elements that are connected to a non-inverting signal output terminal and an inverting signal output terminal of the differential amplifier, respectively; first to third nonlinear elements each outputting a first logic level if the received signal is equal to or larger than a given threshold value, and outputting a second logic level if the received signal is smaller than the given threshold value; and a logic circuit that outputs the logic level output by the second nonlinear element if the logic levels output by the second and third nonlinear elements are different from each other, and makes the logic level of the output signal unchangeable when the second and third nonlinear elements output the same logic level.
