Abstract
An optical coupling device includes a light receiving element provided with a first output terminal and a second output terminal, a light emitting element provided on the light receiving element, a first switching element, a first electrode plate, and a sealing member. The first switching element is provided side by side on the light receiving element. A first main terminal and a control terminal are provided on an upper surface of the first switching element. A second main terminal is provided on a lower surface of the first switching element. The first main terminal is connected to the first output terminal. The control terminal is connected to the second output terminal. An upper surface of the first electrode plate is connected to the second main terminal. The sealing member covers the light receiving element, the light emitting element, and the first switching element.
