Optocoupler Market by Type (Transistor, Darlington Transistor, TRIAC, SCR, Others) by Application (Consumer Electronics, Automobiles, Aviation, Healthcare and Medical, Others)- Growth, Future Prospects And Competitive Analysis, 2016 - 2028

Photocoupler is an electric component that facilitates the transmission of the electrical signal using light between two isolated circuits called an Optocoupler. It is also known as an optical isolator or optoisolator. The most common form of Optocoupler has primarily consisted of LED & Phototransistor. Near Infrared LED is an integral part of an Optocoupler, which convert an electrical signal into light. In contrast, a photosensor is another essential component that detects the input light and generates electrical energy. The history of optocouplers dates back five decades. It was developed and commercialized in the 1970s.      


The Global Optocoupler market is expected to witness a CAGR of 7.5% during the forecast period. The revenue generated by the global Optocoupler market in 2021 was over USD 2,680.74 million and is expected to generate revenue worth USD 4,614.75 million in 2028.
