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 premolded cavities with a light-coupling medium contained therein. Walls of the one or more premolded cavities advantageously help shape the light-coupling medium during manufacture, therefore, resulting in a light path with controlled shape and dimensions.

Premolded cavity for optoelectronic device

A coupler is disclosed that employs hall-effect sensing technology. Specifically, the coupler is configured to produce an output voltage by converting the magnetic field generated by a current conductor at an input side. The output and input sides may be electrically isolated from one another but may be coupled via the hall-effect sensing technology, such as a hall-effect sensor.

Hall-effect sensor isolator

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 may include an interruption in the insulation of the opto-coupler between the light source and the light detector. In addition, this interruption may further include a efficiency enhancer, or lens, to direct light emitted from the light source. Accordingly, the creepage distance and operational voltages of the opto-coupler can be increased while maintaining high efficiency levels.

Face-to-face opto-coupler device and method of manufacture

In an embodiment, the invention provides a coil transducer isolator package comprising at least one lead frame, at least two integrated circuits (ICs) and a flex circuit comprising at least a first coil transducer. The first coil transducer comprises at least one metal coil. The coil transducer isolator package is fabricated such that no portion of the lead frame is physically located within a spatial volume extending substantially perpendicular to the at least one metal coil. The boundaries of the spatial volume are defined by a periphery of the at least one metal coil. At least one of the two ICs is at least partially located within the spatial volume extending substantially perpendicular to the at least one metal coil.
