SI8275GAD-IM1R

Isolators - Gate Drivers Overview

The SI8275GAD-IM1R is a dual-channel digital isolator gate driver from the Si827x series, manufactured by Skyworks Solutions. It utilizes radio frequency (RF) coupling technology to provide galvanic isolation with a rated voltage of 1000Vrms. The device features a peak output current of 4A and supports an output supply voltage range of 4.2V to 30V. Key electrical parameters include a maximum propagation delay of 60ns for both high-to-low and low-to-high transitions, with a typical rise time of 10.5ns and fall time of 13.3ns. It operates within a temperature range of -40°C to 125°C and is housed in a 14-QFN (5x5) package.

• Power supply circuits

Isolators - Gate Drivers Procurement Notes

Verify component authenticity through authorized Skyworks distributors or certified partners. Confirm that the specific ordering suffix matches the required isolation voltage and package variant. Check for recent Product Change Notifications (PCN) regarding manufacturing site transfers or material updates. Ensure compliance with RoHS standards and relevant safety certifications such as UL, CSA, VDE, and CQC before integration into final designs.

Isolators - Gate Drivers Selection Notes

Select this model when a 1000Vrms isolation rating is sufficient for the application, distinguishing it from higher-voltage variants like the SI8275GB. Consider the 4A peak drive capability for driving medium-power MOSFETs or IGBTs. Evaluate the 60ns propagation delay against system timing requirements. The 14-QFN package requires appropriate PCB thermal management and soldering profiles suitable for surface mount technology.
