SI86S662BC-IS1R

Digital Isolators Overview

The SI86S662BC-IS1R is a six-channel digital isolator from the Si86S6x automotive series, manufactured by Skyworks Solutions. It utilizes capacitive coupling technology to provide electrical isolation with a rated insulation voltage of 3750 Vrms. The device supports unidirectional signal transmission at data rates up to 150 Mb/s and features a common-mode transient immunity (CMTI) of 100 kV/µs. Operating within a supply voltage range of 2.5 V to 5.5 V, it is housed in a 16-pin SOIC narrow package. The component is qualified under AEC-Q100 standards for automotive applications.

Digital Isolators Feature Summary

• Automotive-grade qualification ensuring reliability for vehicle electronics environments
• High common-mode transient immunity for noise-resistant signal integrity
• Capacitive coupling isolation providing robust barrier performance

Digital Isolators Applications

• Automotive powertrain control systems
• Inverter gate drive interfaces
• On-board charging (OBC) circuits

Digital Isolators Procurement Notes

Verify the specific suffix IS1R corresponds to the required tape-and-reel packaging configuration. Confirm that the BC variant meets the necessary temperature and voltage specifications for the target design. Ensure compliance with RoHS directives and check for any recent product change notices affecting lead times or material composition before finalizing procurement orders.

Digital Isolators Selection Notes

Select this component when high channel density and automotive certification are required. The six-channel configuration reduces board space compared to single-channel alternatives. Verify that the 150 Mb/s data rate suffices for the application's communication speed. Ensure the 3750 Vrms isolation rating exceeds the system's working voltage requirements to maintain safety margins.

Digital Isolators Part Context

This part belongs to the Si86S6x family, which is specifically designed for automotive applications. Unlike general-purpose isolators, these devices undergo rigorous testing to meet AEC-Q100 standards. The family offers various channel counts and isolation voltages, allowing designers to scale solutions while maintaining consistent interface characteristics across different system modules.

Digital Isolators Replacement Considerations

Direct substitutes include other parts within the Si86S6x family, such as the SI86S662BB-IS1R, which offers similar functionality but with a lower 2500 Vrms isolation rating. Designers must verify that the reduced isolation voltage of alternative parts remains sufficient for their specific circuit requirements.
