PHOTORELAY

摘要

A photorelay includes an insulation board, input and output terminals, a die pad portion, a light receiving element, a light emitting element, a MOSFET, and a first sealing resin layer. The insulation board has first and second surfaces. The input terminal includes a first conductive region. The output terminal includes a first conductive region. The light receiving element is bonded on the die pad portion. The light emitting element is bonded on an exposed surface of the light receiving element, and connected to the first conductive region of the input terminal. The MOSFET is connected to the first conductive region of the output terminal. A connecting electrode is included as a part of the input or output terminal. Attachment conductive regions included respectively in the input and output terminals are provided on a side surface of the insulation board as the attachment surface of the photorelay to a wiring substrate.
