SI8237BD-B-IS

Isolators - Gate Drivers Overview

The SI8237BD-B-IS is a dual-channel, galvanically isolated gate driver manufactured by Skyworks Solutions Inc. It utilizes capacitive coupling technology to provide robust signal isolation with a rated voltage of 5000 Vrms. The device features two independent channels capable of sourcing and sinking peak output currents up to 500 mA. It operates within an extended temperature range of -40°C to +125°C and is housed in a 16-SOIC package. Key electrical specifications include a maximum propagation delay of 60 ns and a minimum common-mode transient immunity of 20 kV/µs.

Isolators - Gate Drivers Feature Summary

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'B' indicates the correct UVLO threshold and pinout variant compared to other SI823x revisions. Confirm that the 'IS' designation matches the required 16-SOIC package width and lead form. Ensure the procurement source provides valid RoHS compliance documentation and material declarations consistent with Skyworks manufacturing standards for this automotive-grade component.

Isolators - Gate Drivers Selection Notes

Select this component when high common-mode transient immunity is critical for noise rejection in switching environments. The 500 mA peak drive current supports medium-power MOSFETs and IGBTs. Consider the 16-SOIC footprint for PCB layout constraints. Verify input logic compatibility and ensure supply voltages align with the specified operating range for both input and output domains.

Isolators - Gate Drivers Part Context

This part belongs to the Si823x family of isolated gate drivers from Skyworks Solutions. The family emphasizes reliability in harsh electrical environments through advanced capacitive isolation. The SI8237BD-B-IS specifically targets applications needing dual-channel isolation with automotive certification, distinguishing it from non-automotive variants or single-channel models within the broader portfolio.

Isolators - Gate Drivers Replacement Considerations

The SI8237BD-B-ISR serves as the reel-pack equivalent of this tube-pack component. Other SI8237 variants may differ in UVLO thresholds or packaging; verify datasheet parameters before substitution.
