Optocouplers are electronic components which use light waves to provide electrical isolation while transferring an electrical signal. They are sometimes known as opto-isolators, photocouplers, or ...

Everlight Electronics' family of phototransistor optocouplers is composed of 21 devices grouped into the 4N2X, 4N3X, H11AX and CNY17-X, CNY17F-X series, all suited for industrial and control designs.

Avago Technologies would like to showcase three optocouplers that deliver robust electrical signal isolation for Intelligent Power Module (IPM) interface applications. The new ACPL-x484 optocouplers ...

This white paper discusses the use of hermetic optocouplers in military and space electronics applications. The use of hermetic optocouplers provide a highly reliable result compared to its plastic ...

Switching power supplies, operating directly from input power lines, are generally required to have their outputs galvanically isolated from the input, in order to reduce the danger of electrical ...

In LEDs heat and high currents hasten the dimming process which can lead to unreliable operation in LED-powered optocouplers. Some simple and straight-forward analysis will keep their light shining ...
