SI8630EC-B-IS1R

Digital Isolators Overview

The SI8630EC-B-IS1R is a general-purpose digital isolator from Skyworks Solutions, featuring three unidirectional channels in a 16-pin SOIC-Narrow package. It provides 3750 Vrms isolation voltage with capacitive coupling technology. 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 and 35 kV/µs common-mode transient immunity. It functions reliably across an extended temperature range from -40°C to +125°C.

Digital Isolators Feature Summary

• Provides galvanic isolation between circuits using high-reliability capacitive coupling technology
• Supports high-speed digital signal transmission with low propagation delay characteristics
• Ensures system safety through high insulation voltage ratings for robust noise immunity

Digital Isolators Applications

• General-purpose digital isolation in industrial automation systems
• Signal isolation in power supply control circuits
• Data communication interfaces requiring high common-mode transient immunity

Digital Isolators Procurement Notes

Verify the specific suffix 'IS1R' confirms the reel packaging format when sourcing components. Ensure that the 3750 Vrms isolation rating aligns with your system's safety requirements. Confirm compatibility with the 2.5 V to 5.5 V supply voltage range for your target application logic levels. Check for AEC-Q100 qualification if automotive reliability standards are required for your deployment.

Digital Isolators Selection Notes

Select this component when three isolated channels are needed for unidirectional signal paths. The 150 Mb/s data rate suits most standard communication protocols. Consider the 16-pin SOIC-Narrow package for space-constrained PCB layouts. The wide operating temperature range makes it suitable for harsh environmental conditions compared to commercial-grade alternatives.

Digital Isolators Part Context

This part belongs to the SI863x series of digital isolators from Skyworks Solutions. It shares the same core capacitive isolation technology as other members like the SI8630EC-B-IS1 but differs in packaging configuration. The series is designed to replace traditional optocouplers in modern electronic designs.

Digital Isolators Replacement Considerations

Direct pin-to-pin replacements may include the SI8630EC-B-IS1 variant, which offers identical electrical specifications but utilizes tape-and-reel packaging instead of cut tape or mouse reel formats. Verify package dimensions and lead finish compatibility before substitution.
