SI86SL40BC-AS1R

Digital Isolators Overview

The SI86SL40BC-AS1R is a low-power, automotive-grade digital isolator from Skyworks Solutions. It features four independent channels with unidirectional signal flow, providing galvanic isolation between circuits. The device utilizes capacitive coupling technology to achieve a reinforced isolation voltage of 3750 VRMS. It supports data rates up to 150 Mbps and offers a minimum common-mode transient immunity of 150 kV/µs. Packaged in a 16-pin SOIC-NB (0.154 inch width) surface-mount format, it is designed for robust performance in demanding environments.

• Robust noise immunity with 150 kV/µs common-mode transient rejection

Digital Isolators Applications

• Automotive electronic control units (ECUs)
• Inverter gate drive isolation
• Industrial communication bus interfaces
• Motor control systems

Digital Isolators Procurement Notes

Verify the specific suffix AS1R corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the SOIC-NB package dimensions align with the target PCB footprint constraints. Ensure compliance with RoHS directives and moisture sensitivity level ratings prior to soldering. Cross-reference the manufacturer's latest datasheet for any updates on recommended soldering profiles or storage conditions.

Digital Isolators Selection Notes

Select this component when high-speed isolation is required alongside strict power budget constraints. The 150 Mbps data rate suits applications needing faster response times than standard isolators provide. The automotive qualification makes it suitable for vehicle networks where long-term reliability under thermal stress is critical. Consider the 16-pin package size if board space allows for wider spacing compared to smaller packages.

Digital Isolators Part Context

This part belongs to the Si86SL4x series of low-power digital isolators. It shares the same family architecture as other variants like the SI86SL41, differing primarily in channel configuration or specific electrical characteristics. The series is designed to replace optocouplers in modern designs, offering superior speed and lower power dissipation while maintaining safety isolation requirements.

Digital Isolators Replacement Considerations

Direct pin-to-pin replacements within the same series include the SI86SL41BC-AS1R. Verify functional equivalence regarding channel directionality and propagation delay specifications before substitution. Ensure that any alternative part maintains the same automotive grade certification and isolation voltage rating.
