Procurement Notes

Verify the specific suffix against official Skyworks documentation to confirm pinout and functional configuration. Ensure the component meets AEC-Q100 automotive standards if required by the application. Cross-reference the datasheet revision date to validate parameter accuracy before integration into final designs.

Selection Notes

Select this component when unidirectional isolation is sufficient for the system architecture. The 100 Mb/s data rate supports standard industrial communication speeds. Consider the 20-pin SOIC footprint for PCB layout constraints. Verify that the 3750 Vrms insulation rating aligns with safety requirements.

Part Context

This part belongs to the Si88620 series of digital isolators. It shares the family's core capacitive isolation technology but is configured specifically for unidirectional applications. The BC suffix typically denotes specific channel configurations within the broader product line.

Replacement Considerations

Consult official Skyworks substitution guides for verified alternatives. Generic equivalents may not match the specific CMTI or insulation ratings.
