PCBA Device-What are the performance characteristics of optocouplers
Optocouplers, also known as optoisolators, are electronic devices that provide electrical insulation between the input and output circuits. They consist of a light-emitting diode (LED) and a photosensitive device, such as a phototransistor, photodiode, or photomOSFET. The LED converts electrical signals into light, which is then detected by the photosensitive device, converting the light back
