Surge Suppression ICS Procurement Notes

Verify availability through authorized distributors as supply status may vary. Confirm that the specific suffix matches the required voltage rating and package type. Ensure compatibility with existing PCB footprint and thermal management requirements before finalizing procurement decisions.

Surge Suppression ICS Selection Notes

Select this component when a 400V working voltage rating is required for transient suppression. The integrated internal switch offers faster response times compared to standard TVS diodes. Consider the compact DFN package size for space-constrained designs requiring high-reliability protection.

Surge Suppression ICS Part Context

This part belongs to the TBU-KE series of high-speed protectors manufactured by Bourns. The series is designed to provide superior transient voltage suppression compared to conventional components. The KE variant specifically targets applications requiring fast response and high energy handling within a small form factor.

Surge Suppression ICS Replacement Considerations

Direct substitutes include other parts within the Bourns TBU-KE series with matching voltage ratings. Verify pinout compatibility and package dimensions when considering alternative manufacturers. Ensure replacement components meet the same UL compliance standards.
