Image of Skyworks Solutions Si871x Digital Isolators Skyworks Solutions Si871x family of digital isolators provides a drop-in replacement solution for optocouplers. The Si871x devices provide superior noise immunity, more robust performance, and greater reliability than optocouplers. They are also the first optocoupler replacements based on mainstream CMOS technology and incorporating an innovative LED emulator front-end.

The Si871x isolators offer ideal configurations, packages, and footprints to replace a wide range of optocoupler products used in solar power inverters, switched mode power supplies (SMPS), uninterruptible power supplies (UPS), industrial drives, programmable logic controllers (PLC) and high-voltage medical equipment.

Applications

Industrial and motor drive
Power converters (SMPS, UPS)
Automotive
Consumer electronics
General purpose I/O
