Optoelectronic device and method of manufacture

摘要

An optoelectronic device is disclosed. The optoelectronic device may be employed as a single or multi-channel opto-coupler that electrically isolates one circuit from another circuit. The opto-coupler may include one or more folded leads that establish an enhanced isolation gap. The enhanced isolation gap increases the creepage distance of the opto-coupler and increases operational voltages that can be accommodated by the opto-coupler.

主权项

1. An opto-coupler device having a major length and width in a first plane and a thickness in a second plane that is orthogonal to the first plane, the opto-coupler device comprising:
a leadframe comprising one or more input leads that are electrically isolated from one or more output leads; a light source configured to emit light according to electrical signals received from the one or more input leads, wherein the light source is mounted to a bonding surface of a first lead, the first lead being in the one or more input leads; a light detector configured to detect light emitted by the light source and convert the detected light into electrical signals for transmission by the one or more output leads, wherein the light detector is mounted to a bonding surface of a second lead, the second lead being in the one or more output leads; and an enhanced isolation gap established between the first lead and the second lead and corresponding to a shortest linear distance between the first lead and second lead, wherein at least one of the first and second lead are folded such that the bonding surface of the folded lead is not co-planar with the first plane, and wherein the enhanced isolation gap comprises a measurable width in the first plane, wherein the first lead and second lead are folded in a common direction away from the first plane and toward the second plane.
