SI86S661EC-IS1R

Digital Isolators Overview

The SI86S661EC-IS1R is a Skyworks Solutions automotive-grade digital isolator featuring six unidirectional channels. It utilizes capacitive coupling technology to provide high-speed signal isolation with a data rate of 150 Mb/s and common-mode transient immunity of 100 kV/µs. The device operates within a supply voltage range of 2.25 V to 5.5 V and offers reinforced insulation capabilities rated at 3750 Vrms. Packaged in a 16-pin SOIC (0.154" width) reel, it supports general-purpose applications requiring robust electrical isolation in demanding environments.

Digital Isolators Procurement Notes

Verify the specific suffix IS1R corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the automotive grade designation aligns with project reliability standards. Ensure compatibility with the specified 16-SOIC footprint during PCB layout validation. Cross-reference the manufacturer's latest datasheet for any updates regarding environmental compliance or pinout configurations prior to final procurement.

Digital Isolators Selection Notes

Select this component when six isolated bidirectional paths are not required, as it provides only unidirectional channels. Choose based on the need for 150 Mb/s throughput and 100 kV/µs CMTI in an automotive context. Consider the SOIC-16 package constraints and reflow soldering profiles. Evaluate if the 3750 Vrms insulation rating meets the system's safety isolation requirements compared to lower-rated alternatives.

Digital Isolators Part Context

This part belongs to the Si86S6x series of automotive digital isolators from Skyworks Solutions. It complements other variants like the SI86S661EC-AS1R by offering specific packaging options while maintaining core performance metrics. The series focuses on providing reliable isolation solutions for electric vehicles and industrial applications where high transient immunity and speed are critical.

Digital Isolators Replacement Considerations

Direct substitutes include SI86S661EC-AS1R and SI86S661EC-IS1, which share identical functional specifications but differ in packaging formats such as tube versus reel. Verify that any replacement maintains the same SOIC-16 footprint and electrical characteristics to ensure board-level compatibility without redesign.
