SI8286CD-ISR

Isolators - Gate Drivers Overview

The SI8286CD-ISR is a single-channel isolated gate driver from Skyworks Solutions, designed for SiC and IGBT applications. It features capacitive coupling technology with 5000Vrms isolation voltage and AEC-Q100 automotive qualification. The device operates within a supply voltage range of 13.2V to 30V and delivers a peak output current of 4A. Key electrical parameters include a maximum propagation delay of 50ns, rise time of 5.5ns, and fall time of 8.5ns. It functions reliably across an extended temperature range of -40°C to +125°C and is housed in a 16-SOIC package.

Isolators - Gate Drivers Feature Summary

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'CD-ISR' against official Skyworks documentation to confirm pinout, isolation rating, and packaging details. Ensure compatibility with system isolation requirements and thermal management needs. Confirm that the 16-SOIC package aligns with PCB layout constraints. Validate that the component meets all necessary regulatory standards for the intended application environment.

Isolators - Gate Drivers Selection Notes

Select this component when high-speed switching with robust isolation is required for wide-bandgap semiconductors. The 4A peak drive current supports moderate-power devices efficiently. Consider the 5000Vrms isolation barrier for safety-critical designs. The automotive qualification makes it suitable for demanding environmental conditions compared to standard industrial variants.

Isolators - Gate Drivers Part Context

This part belongs to the SI828x ISOdriver family, which utilizes Skyworks' proprietary capacitive isolation technology. Unlike magnetic or optical isolators, this architecture offers superior longevity and performance stability. The SI8286 variant specifically targets high-performance gate driving needs in modern power conversion architectures.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes within the same series include SI8286CC-ISR, which shares similar electrical characteristics but may differ in isolation voltage ratings or certification packages. Verify functional equivalence before substitution.
