1. A photocoupler, comprising:
a substrate including an insulating layer, an input terminal, and an output terminal; a MOSFET provided on the substrate, the MOSFET having a first surface having a first electrode pad and a first bonding region; a light receiving element provided on the first bonding region, the light receiving element having a first surface and a second surface opposite to the first surface, the first surface including a first region, a second region, and a first electrode being located at the second region; a light emitting element electrically connected to the input terminal, the light emitting element having a first surface and a second surface opposite to the first surface, the first surface including a first electrode and a second electrode, the second surface having a light emitting region of emitted light; a bonding layer configured to bond the light emitting element to the first region of the light receiving element; and a first bonding wire coupling the first electrode pad of the MOSFET to the first electrode of the light receiving element, wherein the light emitting element overlaps a portion of the light receiving element, and the MOSFET. |
