Si8661BD-B-IS
Overview
The Si8661BD-B-IS is a high-performance, six-channel digital isolator providing 5000Vrms isolation using Skyworks proprietary capacitive coupling technology. It supports data rates up to 150Mbps with a 5/1 directional configuration, making it ideal for isolating high-speed digital buses while maintaining signal integrity. This industrial-grade component operates from 2.5V to 5.5V and features high common-mode transient immunity of 35kV/us.
Why Choose This Part
The Si8661BD-B-IS offers superior reliability over optocouplers by providing lower propagation delays, reduced power consumption, and a much longer service life. With 150Mbps throughput and 5000Vrms isolation in a wide-body SOIC-16 package, it meets stringent safety requirements while occupying minimal board space for six-channel isolation.
Applications
Key Specifications
Getting Started
When designing with the Si8661BD-B-IS, ensure both VDD1 and VDD2 are decoupled with 0.1uF and 1uF capacitors placed as close to the pins as possible. For evaluation, the Si86xxISO-KIT provides a hardware platform to test signal integrity and power consumption across various supply voltages. Follow PCB layout guidelines for high-voltage creepage and clearance as defined by the 7.50mm wide-body SOIC footprint.
