PC817X3NSZ2B Sharp

The PC817X3NSZ2B is a 4-pin optocoupler manufactured by Sharp. It is a dual-channel device that provides isolation between devices in different circuits. The optocoupler consists of an IC (integrated circuit) containing two infrared light emitting diodes (LED) that are optically coupled to a pair of a silicon photodetector.The RoHS stands for Restriction of Hazardous Substances, which is an EU environmental regulation that sets limits on the use of certain hazardous substances found in electrical and electronic equipment. In compliance with the RoHS directive, this optocoupler does not contain lead or other hazardous substances. The optocoupler is also available in a DIP-4 (dual in-line package), which allows it to be inserted into a small space on a printed circuit board (PCB). This makes the optocoupler suitable for applications where space is limited. The PC817X3NSZ2B allows for electrical isolation, making it suitable for protecting low-voltage circuitry from the influence of high-voltage components in the same circuit. It is commonly used for EMI (electromagnetic interference) suppression and noise elimination.
