SI8271GA-ASR

Isolators - Gate Drivers Overview

The SI8271GA-ASR is a single-channel, galvanically isolated gate driver from Skyworks Solutions. It utilizes silicon isolation technology to provide high common-mode transient immunity and low latency. The device operates with an input voltage range of 2.5 V to 5.5 V and supports output supply voltages up to 30 V. Key electrical parameters include a maximum propagation delay of 75 ns, rise time of 16 ns, and fall time of 18 ns. It delivers a peak output current of 4 mA and features a 1 kVrms insulation voltage. The component is housed in an 8-SOIC package and is rated for operation between -40°C and +125°C.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix ASR indicates reel packaging when sourcing. Confirm that the automotive grade designation aligns with project requirements. Ensure compatibility with the required SOIC-8 footprint during PCB layout. Cross-reference the datasheet for any regional distribution restrictions or moisture sensitivity level updates prior to ordering.

Isolators - Gate Drivers Selection Notes

Select this component for applications requiring single-channel isolation with high CMTI. Compare against other Si827x variants if higher voltage ratings or dual-channel configurations are needed. Consider the 4 mA output drive capability relative to the target gate charge requirements. Verify thermal performance within the specified operating temperature range.

Isolators - Gate Drivers Part Context

This part belongs to the Si827x family of isolated gate drivers. It shares architectural similarities with models like the SI8271GA-IS but differs in packaging format. The series is designed for industrial and automotive environments where reliable signal isolation is critical. It complements other Skyworks isolation products by offering a balance of speed and robustness.

Isolators - Gate Drivers Replacement Considerations

The SI8271GA-IS serves as a tube-packaged alternative within the same functional family. Check pinout compatibility and parameter equivalence before substitution.
