SI86S620FC-IS

Digital Isolators Overview

The SI86S620FC-IS is a general-purpose digital isolator from the Si86S6x series, manufactured by Skyworks Solutions Inc. It features two unidirectional channels with capacitive coupling technology and operates within a supply voltage range of 2.25 V to 5.5 V. The device provides an isolation voltage of 3750 Vrms and supports data rates up to 10 Mbps. Key electrical parameters include a maximum propagation delay of 41.5 ns, typical rise and fall times of 2.5 ns, and a common-mode transient immunity of 150 kV/µs. It functions reliably across an operating temperature range of -40°C to +125°C and is housed in an 8-SOIC package.

Digital Isolators Feature Summary

• Provides galvanic isolation between circuits using capacitive coupling technology for signal transmission.
• Features two independent unidirectional signal channels for bidirectional communication support.
• Offers high common-mode transient immunity to maintain signal integrity in noisy environments.
• Designed for automotive applications with specific qualification standards.

Digital Isolators Applications

• Automotive electronic control units requiring isolated communication interfaces
• Industrial automation systems needing reliable signal isolation
• Power electronics monitoring and control circuits

Digital Isolators Procurement Notes

Verify the exact suffix (IS) against your bill of materials, as it denotes tube packaging which differs from reel variants like ASR. Confirm that the 10 Mbps data rate meets your system requirements, as higher-speed alternatives exist in the same family. Ensure the 8-SOIC footprint matches your PCB layout constraints. Check current availability status, as automotive-grade components may have restricted supply or longer lead times depending on the region and distributor.

Digital Isolators Selection Notes

Select this component when a robust, automotive-qualified digital isolator with moderate speed requirements is needed. It is suitable for applications where 10 Mbps is sufficient and cost-effectiveness is prioritized over higher bandwidth options. Consider the 8-SOIC package size for space-constrained designs. Verify that the 3750 Vrms isolation rating aligns with your safety standards and circuit voltage levels. Compare with other Si86S6x variants if different channel counts or packaging formats are required.
