SI8662EC-B-IS1

Digital Isolators Overview

The SI8662EC-B-IS1 is a general-purpose digital isolator from the Si866x series, manufactured by Skyworks Solutions Inc. It utilizes capacitive coupling technology to provide electrical isolation between circuits. The device features six channels configured as four forward and two reverse unidirectional paths. It supports data rates up to 150 Mb/s with a propagation delay of 8 ns. The insulation voltage is rated at 3750 Vrms. Operating supply voltages range from 2.375 V to 5.5 V. The component is housed in a 16-pin SOIC-Narrow package and is qualified under AEC-Q100 standards for automotive applications.

Digital Isolators Feature Summary

• Capacitive coupling isolation technology for high-speed signal transmission
• AEC-Q100 qualification for automotive reliability requirements
• High common-mode transient immunity capability

Digital Isolators Applications

• Automotive electronic control units
• Industrial communication interfaces
• Power supply feedback loops

Digital Isolators Procurement Notes

Verify the specific suffix IS1 against the manufacturer datasheet to confirm the tube packaging format and moisture sensitivity level. Ensure the order matches the exact part number including all case-sensitive characters to avoid receiving variants with different insulation ratings or channel configurations within the same family.

Digital Isolators Selection Notes

Select this component when an AEC-Q100 qualified digital isolator with 3750 Vrms isolation is required for automotive designs. The 4F/2R channel configuration suits applications needing more forward than reverse isolation paths. Compare against the SI8662BD variant if higher 5 kV insulation is needed, noting that the BD version may have different thermal or pinout characteristics.

Digital Isolators Part Context

This part belongs to the Si866x family of digital isolators from Skyworks Solutions. These devices are designed to replace traditional optocouplers in high-speed digital isolation applications. The family offers various channel counts and insulation voltage ratings to suit different system isolation requirements while maintaining small form factors.

Digital Isolators Replacement Considerations

The SI8662BD-B-IS1 is a related part offering 5 kV isolation instead of 3.75 kV. Verify pin compatibility and insulation specifications before substitution.
