In summary, the Si87xx family is a CMOS solution with advantages over traditional optocouplers, such as high reliability. Readily available CMOS process technologies are used, resulting in a low FIT rate. The architecture provides an improvement of as much as 75% in common-mode transient immunity. The capacitive isolation technology is rated to withstand up to 5 kV and is IEC 60747-5-2 compliant, including 10 kV surge protection. These devices are available in multiple package options and output configurations. Typical applications for the Si87xx family include general I/O in programmable logic controllers or data acquisition systems, motor control systems, and switch-mode power supplies.
