SI8652BC-B-IS1

Digital Isolators Overview

The SI8652BC-B-IS1 is a five-channel digital isolator from the Si865x series, manufactured by Skyworks Solutions Inc. It utilizes capacitive coupling technology to provide electrical isolation with a rated insulation voltage of 3750 Vrms. The device supports a data rate of 150 Mb/s and features a maximum propagation delay of 8 ns. It operates within a supply voltage range of 2.375 V to 5.5 V and functions across an extended temperature range from -40 °C to +125 °C. Packaged in a 16-lead SOIC-Narrow (SOIC-16) surface-mount format, it includes three forward and two reverse channels.

Digital Isolators Feature Summary

• Provides robust galvanic isolation via capacitive coupling technology for signal integrity
• Supports high-speed data transmission up to 150 Mb/s with low propagation delay
• Configured with five unidirectional channels, specifically three forward and two reverse paths
• Complies with AEC-Q100 automotive qualification standards for reliability

Digital Isolators Applications

• Automotive electronic control units requiring isolated communication interfaces
• Industrial automation systems needing reliable signal isolation between controllers
• Power conversion circuits where high common-mode transient immunity is critical
• Medical equipment requiring safe patient isolation barriers

Digital Isolators Procurement Notes

Verify the specific suffix B-IS1 confirms the SOIC-Narrow-16 package and tube packaging configuration. Ensure the order matches the 3750 Vrms insulation rating rather than higher-rated variants like the BD series. Confirm RoHS compliance status and AEC-Q100 certification requirements for your specific application environment before finalizing procurement.

Digital Isolators Selection Notes

Select this component when a five-channel isolator with automotive qualification is required. The 3750 Vrms rating suits most industrial and automotive applications, whereas higher isolation voltages require the BD series. The narrow SOIC package offers space efficiency compared to wide packages. Verify that the 150 Mb/s data rate meets system timing constraints and that the 2.375 V minimum supply voltage aligns with the logic levels used in the design.

Digital Isolators Part Context

This part belongs to the Si865x family of digital isolators, which are designed for general-purpose isolation tasks. The family shares similar core technologies but varies in channel count, isolation voltage ratings, and package types. The SI8652 variant specifically provides five channels, distinguishing it from four-channel or dual-channel counterparts within the same product line.
