SI8275DA-IM1R

Isolators - Gate Drivers Overview

The SI8275DA-IM1R is a dual-channel digital isolator gate driver from Skyworks Solutions, utilizing RF coupling technology for galvanic isolation. It features a 2500Vrms isolation voltage and high common-mode transient immunity of 150kV/µs. The device operates with a supply voltage range of 4.2V to 30V and delivers peak output currents of 1.8A (high) and 4A (low). Key timing parameters include a maximum propagation delay of 60ns, rise time of 10.5ns, and fall time of 13.3ns. It is housed in a 14-QFN (5x5mm) surface-mount package and supports operating temperatures from -40°C to +125°C.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'IM1R' against official Skyworks documentation to confirm tape-and-reel packaging and exact electrical characteristics. Cross-reference the datasheet revision date to ensure compliance with current manufacturing standards. Confirm that the 14-QFN footprint matches your PCB design requirements prior to finalizing procurement orders.

Isolators - Gate Drivers Selection Notes

Select this component when high-voltage isolation combined with fast switching speeds is required. The dual-channel configuration simplifies layout for half-bridge or full-bridge topologies. Ensure the input logic levels are compatible with the 2.5V to 5.5V range and verify that the thermal dissipation capabilities of the QFN package suit the application's power density constraints.

Isolators - Gate Drivers Part Context

This part belongs to the Si827x family of isolated gate drivers designed for demanding industrial applications. It replaces older optocoupler-based solutions by offering superior reliability, smaller form factor, and consistent performance over temperature variations. The series is engineered to meet stringent safety certifications including UL, CSA, and VDE standards for industrial equipment.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes within the same family include the SI8275DA-IM1 in tray packaging. For pin-compatible alternatives with different isolation ratings, consider the SI8274 series. Verify that any replacement maintains the 2500Vrms isolation rating and similar timing characteristics to avoid redesigning the control loop.
