  • Optocoupler
    Patent number: 8577190
    Abstract: An optocoupler having an optical transmitter die, an optical receiver die, a light guide, a limiting element and a body is disclosed. The light guide is confined to upper portion of the body by using the limiting element. In one embodiment, the limiting element is a dielectric tape. In yet another embodiment, the limiting element is a pre-molded plastic attached to the lead frame via non-conductive epoxy. The use of the limiting element yields light guides having consistent shape.
