This is a PC817 Optocoupler. It is available in DIP-4 Package. An optocoupler is a device which operates due to light, its design is such that, it has LED on input side, and photo driver on output side. Now, when the current flows on the input side, the LED glows, and puts light on the photo transistor, which turns on and drives the output.
It has an isolation of 5000V between input and output. It also has high collector emitter voltage of 80V. The Current Transfer Ratio of PC817 is: 50% to 600%.
