SI86S630EC-IS1R

Digital Isolators Overview

The SI86S630EC-IS1R is a Skyworks Solutions digital isolator featuring three unidirectional channels with capacitive coupling technology. It provides an insulation 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, exhibiting a propagation delay of 8 ns. Designed for automotive applications, it holds AEC-Q100 qualification and functions reliably between -40°C and +125°C. Packaged in a 16-SOIC narrow body reel, this component ensures robust signal isolation in high-noise environments.

Digital Isolators Feature Summary

• Capacitive coupling architecture enables high-speed digital signal transmission with superior noise immunity compared to optical alternatives.
• Automotive-grade reliability certified under AEC-Q100 standards for operation in demanding thermal and electrical conditions.
• Integrated logic features include input hysteresis and output state indication to ensure stable signal integrity during transient events.

Digital Isolators Applications

• Automotive powertrain control modules requiring isolated communication interfaces
• Inverter gate drive circuits in electric vehicle traction systems
• Industrial motor drives and servo controller isolation barriers

Digital Isolators Procurement Notes

Verify the specific suffix IS1R confirms the reel packaging format required for automated assembly processes. Confirm that the EC designation aligns with the extended temperature range specifications necessary for your target application environment. Ensure compatibility with the 16-SOIC narrow body footprint during PCB layout verification to prevent mechanical interference.

Digital Isolators Selection Notes

Choose this model when unidirectional signal flow is sufficient for the isolation barrier design. The 150 Mb/s data rate supports high-frequency protocols such as CAN FD or SPI without additional buffering requirements. Consider the low propagation delay for precise timing synchronization in switching power supplies or motor control loops where minimal latency is critical.

Digital Isolators Part Context

This component belongs to the Si86S6x series of automotive-qualified digital isolators from Skyworks Solutions. The series utilizes proprietary silicon dioxide (SiO2) isolation technology to replace traditional optocouplers. This family offers improved performance metrics including lower power consumption, smaller form factors, and greater consistency in electrical characteristics across manufacturing batches.

Digital Isolators Replacement Considerations

Direct functional substitutes within the same automotive series include the SI86S630BC-IS1R variant, which shares identical channel count and isolation ratings but may differ in specific qualification documentation or package tolerance details. Verify pinout compatibility before substitution.
