SI8273DBD-AS1

Isolators - Gate Drivers Overview

The SI8273DBD-AS1 is a high-speed, galvanically isolated gate driver manufactured by Skyworks Solutions. It features a single channel with high-side and low-side output configuration in an SOIC-16 surface-mount package. The device provides 2.5 kVrms insulation voltage and supports a maximum propagation delay of 75 ns. Key timing parameters include a rise time of 16 ns and a fall time of 18 ns. It operates within a temperature range of -40°C to +125°C, dissipates up to 1.2 W, and draws 10 mA working supply current while delivering 4 mA output current at 12 V.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix AS1 against the manufacturer's official documentation to confirm pinout compatibility and electrical characteristics. Ensure the SOIC-16 package dimensions match your PCB footprint requirements. Confirm that the 2.5 kVrms isolation rating meets the safety standards required for your specific application environment.

Isolators - Gate Drivers Selection Notes

Select this component when a single-channel isolated driver with high CMTI is required. Compare the 75 ns propagation delay against system timing constraints. Verify that the 12 V output voltage level aligns with the target gate drive requirements. Consider the thermal dissipation limits of 1.2 W for the intended operating conditions.

Isolators - Gate Drivers Part Context

This part belongs to the Si8273 series of isolated gate drivers from Skyworks Solutions. The series offers various configurations including single, dual, and high-side/low-side drivers. The DBD suffix indicates the SOIC-16 surface mount package variant, distinguishing it from other package options within the same functional family.

Isolators - Gate Drivers Replacement Considerations

Consult the official Skyworks cross-reference guide for verified substitutes. Direct replacements must maintain identical isolation voltage, package type, and CMTI ratings to ensure circuit compatibility.
