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.

Optocouplers, also known as opto-isolators, are components that transfer electrical signals between two isolated circuits by using infrared light. As an isolator, an optocoupler can prevent high ...

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 ...

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 ...
