SI86SM42BE-IS2R

Digital Isolators Overview

The SI86SM42BE-IS2R is a Skyworks Solutions Inc. digital isolator featuring four unidirectional channels with capacitive coupling technology. It provides a high isolation voltage of 6000 Vrms and supports data rates up to 150 Mbps. The device exhibits a minimum common-mode transient immunity (CMTI) of 100 kV/µs and a maximum propagation delay of 14 ns. Operating within a supply voltage range of 3.135 V to 5.25 V, it functions reliably across an extended temperature range from -40°C to +125°C. This component is supplied in a tape-and-reel package format.

Digital Isolators Feature Summary

• High-voltage isolation capability of 6000 Vrms for robust circuit separation
• Low power consumption design optimized for energy-efficient applications
• High-speed data transmission supporting 150 Mbps unidirectional channels
• Enhanced noise immunity with 100 kV/µs common-mode transient rejection

Digital Isolators Applications

• Automotive electronic systems requiring AEC-Q100 compliance
• Industrial automation control interfaces
• Power supply monitoring and gate drive circuits
• Medical equipment signal isolation

Digital Isolators Procurement Notes

Verify the specific suffix 'IS2R' to confirm the tape-and-reel packaging configuration, as this differs from tube-packaged variants like 'IS2'. Ensure compatibility with automated surface-mount assembly processes due to the reel format. Cross-reference the manufacturer's latest documentation to confirm current production status and any potential obsolescence notices before finalizing procurement plans.

Digital Isolators Selection Notes

Select this component when high-voltage isolation of 6000 Vrms is required alongside low power operation. The 150 Mbps speed and 14 ns delay suit high-frequency digital communication needs. Consider the 100 kV/µs CMTI for environments with significant electrical noise. The SOIC-16 package facilitates standard PCB layout, while the automotive qualification ensures reliability in demanding operational conditions.

Digital Isolators Part Context

This part belongs to the Si86SM4x series of low-power digital isolators from Skyworks Solutions. It utilizes advanced capacitive coupling technology to provide galvanic isolation between circuits. The series is designed to replace traditional optocouplers, offering superior performance in speed, power consumption, and size. The 'SI86SM42BE-IS2R' designation specifically identifies the four-channel unidirectional variant in a reel package.

Digital Isolators Replacement Considerations

The SI86SM42BE-IS2 is a parameter-equivalent alternative available in tube packaging instead of reels. Both parts share identical electrical specifications and functionality. Designers must adjust their assembly process if switching from reel to tube formats, but no circuit redesign is typically necessary due to pin-to-pin compatibility.
