An optocoupler package made up from a pre-assembled package having a leadframe, a voltage isolation barrier, and a body molded from a reflective plastic material. The voltage isolation barrier is fabricated as part of the body and positioned in such a way as to substantially increase the electrical flashover path between the optical source and the optical detector. An optical source mounted in the pre-assembled package subsequent to fabrication of the molded body. An optical detector is optically coupled to the optical source by reflection within the pre-assembled package, the optical detector being mounted in the pre-assembled package subsequent to fabrication of the molded body A reflective plastic cover is bonded to the pre-assembled package.
