PC817 Transistor Output Optocoupler 62K Switched-mode power suppliesPC817 Photocoupler IC has a transistor that is controlled based on light (photon). So this IC basically has an IR (infrared) LED and a photo transistor inside it. When the IR LED is powered the light from it falls on the transistor and it conducts. PC817 IC is used to provide electrical isolation between two circuits, one of which is connected to an IR LED and the other to a phototransistor. The digital signal sent to the IR LED is reflected on the
