SI8622BD-B-ISR

Digital Isolators Overview

The SI8622BD-B-ISR is a Skyworks Solutions digital isolator featuring two independent channels with unidirectional signal paths. It utilizes capacitive coupling technology to provide 5000 Vrms isolation voltage. The device supports data rates up to 150 Mb/s and operates within a supply voltage range of 2.5 V to 5.5 V. Key electrical parameters include an 8 ns propagation delay, 4 ns rise/fall times, and a common-mode transient immunity of 35 kV/µs. It is housed in a 16-pin SOIC-Wide package and is qualified under AEC-Q100 standards for automotive applications.

Digital Isolators Feature Summary

• Provides galvanic isolation via high-reliability capacitive coupling technology
• Supports bidirectional communication through one forward and one reverse channel configuration
• Certified to AEC-Q100 standards for automotive reliability requirements
