SI8622BC-B-ISR
Overview
The SI8622BC-B-ISR is a high-performance, dual-channel digital isolator offering 3750Vrms isolation and a high-speed data rate of 150Mbps. Based on Skyworks' proprietary capacitive coupling technology, it provides robust galvanic isolation with a high common-mode transient immunity (CMTI) of 35kV/us. This device features one forward and one reverse channel (1/1 configuration), making it ideal for bidirectional data communication lines.
Why Choose This Part
This isolator provides superior timing specifications with low propagation delay and low jitter compared to traditional optocouplers. It operates efficiently across a wide 2.5V to 5.5V supply range and maintains low power consumption of approximately 4.4mA per channel at 100 Mbps. The 35kV/us CMTI ensures reliable data integrity even in environments with high-speed switching transients.

Key Specifications
Getting Started
When designing the PCB, place 0.1uF bypass capacitors as close as possible to the VDD1 and VDD2 pins (pins 1 and 8). Maintain the required creepage and clearance distances under the 8-SOIC package to preserve the 3750Vrms isolation rating. For evaluation, use the Si86xxISO-KIT evaluation board to test signal integrity and power consumption across different load conditions.
