SI8630ET-ISR

Digital Isolators Overview

The SI8630ET-ISR is a high-speed digital isolator from Skyworks Solutions, featuring three unidirectional channels in a 16-pin SOIC-Wide package. It supports data rates up to 150 Mb/s with a propagation delay of 8 ns and rise/fall times of 4 ns. The device offers an insulation voltage of 5000 Vrms and withstands a 10 kV surge. It operates on a supply voltage between 2.5 V and 5.5 V, with a maximum power dissipation of 275 mW. The component functions within a temperature range of -40°C to +125°C and utilizes capacitive coupling for isolation.

Digital Isolators Feature Summary

• Provides robust protection against high-voltage transients with a 10 kV surge rating.
• Utilizes capacitive coupling technology for reliable signal transmission across isolation barriers.
• Features low propagation delay and fast transition times for high-speed data integrity.

Digital Isolators Applications

• Industrial automation systems requiring galvanic isolation
• Power electronics control circuits
• General-purpose digital communication interfaces

Digital Isolators Procurement Notes

Verify the specific suffix 'ISR' corresponds to the reel packaging configuration as indicated by distributor listings. Confirm that the 10 kV surge rating aligns with your system's transient immunity requirements. Ensure the SOIC-Wide-16 footprint matches your PCB layout constraints. Cross-reference the 5000 Vrms insulation voltage with applicable safety standards for your target application environment.

Digital Isolators Selection Notes

Select this component when high surge immunity is critical alongside standard 5000 Vrms isolation. The 150 Mb/s data rate suits applications needing faster throughput than lower-speed isolators. The wide operating temperature range makes it suitable for harsh industrial environments. Consider the 16-pin wide package if board space allows for easier soldering compared to narrow variants.

Digital Isolators Part Context

This part belongs to the si863x series of digital isolators from Skyworks Solutions. It shares the core capacitive coupling architecture with other members like the SI8630EC-B-IS1 but differs in insulation ratings and package type. The ET suffix typically denotes enhanced surge performance compared to standard variants in the same channel count family.

Digital Isolators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Direct replacements may require matching the 16-pin SOIC-Wide package, 3-channel configuration, and 150 Mb/s speed specifications from other manufacturers.
