SI8275DAD-IM1R

Isolators - Gate Drivers Overview

The SI8275DAD-IM1R is a dual-channel, high-speed digital isolator gate driver manufactured by Skyworks Solutions Inc. It utilizes radio frequency (RF) coupling technology to provide electrical isolation between input and output circuits. The device features a peak output current of 4A and supports an output supply voltage range from 4.2V to 30V. Key performance specifications include a maximum propagation delay of 60ns for both low-to-high and high-to-low transitions, with a typical rise time of 10.5ns and fall time of 13.3ns. It offers a minimum common-mode transient immunity (CMTI) of 150kV/µs and operates within a temperature range of -40°C to +125°C. The component is housed in a 14-VDFN package.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'DAD' against official Skyworks documentation to confirm pinout and functional equivalence, as variations exist within the Si827x family. Confirm that the reel packaging matches design requirements. Check for end-of-life status or product change notifications prior to finalizing procurement plans.

Isolators - Gate Drivers Selection Notes

Select this component when high-speed switching and robust noise immunity are required in isolated power stages. The 4A peak current capability suits medium-power MOSFET and IGBT driving. Ensure the system ground separation aligns with the 2500Vrms isolation rating. Compare CMTI requirements against other family members if higher immunity is needed.

Isolators - Gate Drivers Part Context

This part belongs to the Si827x series of digital isolators, which leverage Skyworks' proprietary RF coupling technology. This series replaces traditional optocouplers in many applications, offering superior reliability, lower power consumption, and tighter parameter matching across channels compared to legacy technologies.

Isolators - Gate Drivers Replacement Considerations

Official substitutes within the same family include SI8275DA-IM1 and SI8275GBD-IM1R. Verify pin compatibility and specific electrical parameters such as CMTI ratings before substituting, as differences may exist between variants.
