SI86S661BC-AS1

Digital Isolators Overview

The SI86S661BC-AS1 is a six-channel unidirectional digital isolator from the Si86S6x automotive series. It features capacitive coupling with a 3750 Vrms insulation voltage and supports data rates up to 150 Mb/s. Operating on a single supply voltage between 2.5 V and 5.5 V, it utilizes an SOIC-NB-16 package. The device operates within a temperature range of -40°C to +125°C and includes internal transient immunity filtering.

Digital Isolators Feature Summary

• Six unidirectional signal channels for isolated data transmission
• Automotive-grade qualification for high reliability applications
• Capacitive isolation technology providing robust noise immunity
• Integrated transient pulse width filtering for signal integrity

Digital Isolators Applications

• Automotive inverter gate drive control
• On-board charger (OBC) communication interfaces
• Battery management system (BMS) isolation
• Electric vehicle traction motor control units

Digital Isolators Procurement Notes

Verify the specific suffix 'BC' indicates the automotive grade variant and 'AS1' denotes the tube packaging configuration. Confirm RoHS compliance status through official Skyworks documentation. Ensure the SOIC-NB-16 footprint matches your PCB layout requirements before finalizing procurement orders.

Digital Isolators Selection Notes

Select this component when six independent unidirectional channels are required in an automotive environment. The 3750 Vrms isolation rating suits high-voltage power electronics. Compare against the SI86S661EC-AS1 if industrial grade specifications suffice, noting that the BC variant meets stricter automotive reliability standards.

Digital Isolators Part Context

This part belongs to the Si86S6x family of low-power automotive digital isolators. It shares the core capacitive isolation architecture with other members like the SI86S641FC-AS1 but offers six channels instead of four. The NB SOIC package allows for compact design in space-constrained automotive modules.

Digital Isolators Replacement Considerations

The SI86S661EC-AS1 is a verified non-automotive equivalent offering identical electrical performance. Verify package compatibility and thermal characteristics when substituting. No direct pin-compatible alternatives exist within the same channel count without re-evaluating isolation ratings.
