The idea of optically coupling a solid-state optical emitter with a semiconductor sensor was proposed in 1963 by Akmenkalns et al. (US patent 3,417,24

The optocoupler can transmit signals between two circuits that are not in common ground, even if there is a high voltage between the two circuits. Com

The application of optocouplers in the medical industry is extensive and profound. They achieve circuit isolation and coupling through photoelectric c

Optical transistors are inherently slower than optical diodes. The earliest and slowest was the 4N35 optocoupler, which had a rise and fall time of 5
