SI8660BD-ASR

Digital Isolators Overview

The SI8660BD-ASR is a six-channel digital isolator from Skyworks Solutions, designed for automotive applications with AEC-Q100 qualification. It utilizes capacitive coupling technology to provide 5000 Vrms isolation voltage across all channels. The device supports unidirectional data transmission at speeds up to 150 Mb/s with a typical propagation delay of 8 ns. It operates on a single power supply ranging from 2.375 V to 5.5 V and functions within a temperature range of -40°C to +125°C. Packaged in a 16-pin SOIC-Wide format, it offers high-speed general-purpose isolation.

Digital Isolators Procurement Notes

Verify the specific suffix ASR against official Skyworks documentation to confirm tape-and-reel packaging specifications. Ensure the selected variant matches the required insulation voltage rating of 5000 Vrms for the intended safety isolation barrier. Cross-reference the package type with PCB footprint requirements before finalizing procurement orders.

Digital Isolators Selection Notes

Select this component when high-speed unidirectional isolation is required in automotive contexts. The 150 Mbps data rate suits most standard communication protocols. Consider the 16-pin SOIC-Wide package for ease of assembly. Verify that the 5 kV isolation rating meets system safety standards compared to lower-rated alternatives like the SI8660BB series.

Digital Isolators Part Context

This part belongs to the Si866x family of digital isolators, which are known for their reliability and speed. The SI8660BD-ASR specifically targets the automotive sector, distinguishing itself from industrial variants through its AEC-Q100 certification. It complements other Skyworks isolation products by offering a dedicated solution for high-voltage automotive power electronics.
