SI8661EB-AUR

Digital Isolators Overview

The SI8661EB-AUR is an automotive-grade digital isolator from the Si866x series, manufactured by Skyworks Solutions. It features six channels configured as five unidirectional forward and one reverse channel. The device utilizes capacitive coupling technology to provide electrical isolation with a rated insulation voltage of 2500 Vrms. It supports data rates up to 150 Mb/s with a propagation delay of 8 ns. Operating on a supply voltage range of 2.375 V to 5.5 V, it draws a typical operating current of 7.9 mA. The component is housed in a 16-lead SSOP package and is qualified for operation within a temperature range of -40°C to +125°C.

Digital Isolators Procurement Notes

Verify that the specific part number suffix matches the required package type and temperature rating. Confirm automotive grade certification status if critical for the application. Check manufacturer datasheets for latest revision details and ensure compatibility with system voltage levels before integration.

Digital Isolators Selection Notes

Select this component when automotive certification and low power consumption are primary requirements. The 2500 Vrms isolation level suits applications not requiring higher voltage barriers. Ensure the 150 Mb/s data rate meets signal transmission needs. Consider the SSOP package dimensions for PCB layout constraints compared to other pin-compatible variants.

Digital Isolators Part Context

This device belongs to the Si866x family of digital isolators, which offers various isolation voltages and channel configurations. The SI8661EB-AUR specifically targets automotive markets with its robust qualification and low-power profile. It complements other Skyworks isolators that may offer higher voltage ratings or different packaging options for diverse industrial and consumer applications.

Digital Isolators Replacement Considerations

Direct replacements include SI8661EB-AU for tube packaging or SI8661BC-B-IS1 for higher 3750 Vrms isolation. Verify pinout compatibility and thermal characteristics when substituting. Ensure the alternative part maintains the required automotive grade status and functional equivalence.
