SI86S641BE-AS2R

Digital Isolators Overview

The SI86S641BE-AS2R is a Skyworks Solutions automotive-grade digital isolator featuring four unidirectional channels. It utilizes capacitive coupling technology to provide high-voltage isolation with a rated insulation voltage of 6.0 kVrms. The device supports data rates up to 150 Mbps and offers a common-mode transient immunity of 150 kV/µs. Designed for robust performance, it operates within a supply voltage range of 2.25 V to 5.5 V and functions reliably across an extended temperature range from -40°C to +125°C. The component is packaged in a 16-pin SOIC-Wide Body (SOIC-WB) format.

Digital Isolators Procurement Notes

Verify the specific suffix AS2R indicates reel packaging when sourcing. Confirm the 6.0 kVrms rating aligns with system isolation requirements. Ensure the SOIC-WB-16 package dimensions fit the PCB layout constraints. Check for RoHS compliance documentation if required by local regulations. Validate that the automotive grade qualification meets the target application's environmental standards.

Digital Isolators Selection Notes

Select this component when high isolation voltage and automotive certification are mandatory. The 6.0 kVrms rating suits applications requiring significant potential difference separation. The 150 Mbps speed is adequate for standard automotive protocols like CAN FD or LIN. Consider the wide-body package for improved thermal dissipation and creepage distance compared to narrow variants.
