SI86S621HC-IS

Digital Isolators Overview

The SI86S621HC-IS is a dual-channel digital isolator from Skyworks Solutions, featuring unidirectional signal transmission. It provides a basic isolation voltage of 3750 Vrms and supports data rates up to 150 Mb/s. The device operates within a supply voltage range of 2.5 V to 5.5 V and functions across an industrial temperature range of -40°C to +125°C. Packaged in a SOIC-Wide-16 format, it utilizes capacitive coupling technology for galvanic isolation.

Digital Isolators Feature Summary

• Provides robust galvanic isolation between high-voltage and low-voltage domains using capacitive coupling technology.
• Supports high-speed digital signal transmission with unidirectional channel configuration for precise timing control.
• Integrated design eliminates the need for external bootstrap components typically required by similar isolators.

Digital Isolators Applications

• Industrial automation systems requiring reliable signal isolation
• Power electronics interfaces such as motor drives and inverters
• Medical equipment needing enhanced safety isolation standards

Digital Isolators Procurement Notes

Verify the specific suffix 'HC' against official Skyworks documentation to confirm package type and thermal characteristics. Ensure the ordering part number matches the exact datasheet revision. Confirm RoHS compliance status directly with the manufacturer or authorized distributors before finalizing procurement orders.

Digital Isolators Selection Notes

Select this component when unidirectional isolation is sufficient for the application architecture. Consider the SOIC-Wide-16 footprint for PCB layout compatibility. Evaluate the 150 Mb/s data rate requirement against system bandwidth needs. Verify that the 3750 Vrms isolation rating meets the specific safety regulations of the target market.

Digital Isolators Part Context

This device belongs to the Si86Sxx family of digital isolators designed for high-reliability applications. It complements other Skyworks isolation products by offering integrated power management features in select variants, though this specific model focuses on signal isolation capabilities.

Digital Isolators Replacement Considerations

Consult official Skyworks substitution guides for verified equivalents. Cross-reference pinouts and electrical specifications carefully. Do not assume functional compatibility with generic isolators without validating insulation ratings and propagation delays.
