SI82F89ABE-IS3R

Isolators - Gate Drivers Overview

The SI82F89ABE-IS3R is a quad-channel digital isolator from Skyworks Solutions, designed for high-speed data transmission with robust isolation capabilities. It features four independent channels supporting data rates up to 150 Mbps per channel. The device operates with a supply voltage range of 2.25 V to 5.5 V on both the isolated and non-isolated sides. It offers a typical common-mode transient immunity of 100 kV/µs and an isolation rating of 5000 Vrms. The IS3R suffix indicates a specific tape and reel packaging configuration suitable for automated assembly processes.

Isolators - Gate Drivers Feature Summary

Isolators - Gate Drivers Procurement Notes

Verify the exact part number including the IS3R suffix to ensure correct packaging format. Confirm that the required isolation voltage ratings meet your system safety standards. Check for RoHS compliance documentation if environmental regulations apply. Ensure compatibility with your PCB footprint and reflow soldering profile specifications before placing orders.

Isolators - Gate Drivers Selection Notes

Choose this component when multiple isolated channels are needed in a single package. Consider the operating voltage requirements of both sides of the isolation barrier. Evaluate the data rate needs against the 150 Mbps capability. Assess the physical size constraints relative to other available isolator packages.

Isolators - Gate Drivers Part Context

This device belongs to Skyworks' family of digital isolators, which utilize proprietary silicon dioxide (SiO2) insulation technology. These devices replace traditional optocouplers by offering superior performance metrics including lower power consumption, higher speed, and greater reliability over temperature variations. The series supports various channel configurations to suit diverse application requirements.

Isolators - Gate Drivers Replacement Considerations

Direct replacements may include other quad-channel digital isolators from manufacturers like Texas Instruments or Analog Devices. Verify pin-to-pin compatibility and isolation voltage ratings when substituting. Ensure equivalent common-mode transient immunity and data rate specifications are maintained for system functionality.
