Intended for current isolation applications, the Miniflat TCMT11xx series of 4-pin optocouplers features a 2-mm profile, reportedly one of the industry’s thinnest for this type of device. The devices ...

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 ...

In isolated power supplies, optocouplers pass the feedback signal across the isolation boundary. Optocouplers contain both a light-emitting diode (LED) and a photo detector. Current flowing through ...
