High Reliability LED Technology In Optocouplers For HEVs And EVs White Paper

Avago Technology optocouplers have been used in all types of applications, including industrial and those requiring ultra-high, mission critical reliability, such as for super express trains, aerospace and military applications.

Optocouplers were first proven in the first commercial hybrid electrical vehicle in the Toyota Prius. Currently, Avago Technologies R2Coupler optocouplers are being used in recently released models of HEV and EV from Japan, Korea, China, Europe and the United States. In addition, more than 40 automotive companies, including car manufacturers and tier one suppliers, are using or evaluating R2Coupler isolation products.

There is widespread misconception that LEDs are not suited to automotive applications. This perception has arisen because commercial grade LEDs—that are only suitable for consumer applications—have occasionally been applied in automotive environments that should only be served by LEDs designed and manufactured with a high quality testing and control process. This misconception has also been advanced by suppliers of non-optical isolation technologies without supporting evidence.
