TBU-DB055-100-WH-Q

Surge Suppression ICS Overview

The TBU-DB055-100-WH-Q is a board mount surge protector from the TBU-DB-Q series, manufactured by Bourns. It features a dual bidirectional design with a voltage rating of 550V and a current rating of 100mA. The component is AEC-Q101 qualified for automotive applications. It utilizes an SMD/SMT end type in a DFN-6 package measuring 6.5 mm in length, 5.5 mm in width, and 0.9 mm in height. Operating temperatures range from -55°C to +125°C.

Surge Suppression ICS Feature Summary

• Dual bidirectional high-speed protection architecture
• Low capacitance characteristics for signal integrity
• AEC-Q101 qualification for automotive reliability

Surge Suppression ICS Applications

• Automotive protection modules
• Dongles
• Test equipment

Surge Suppression ICS Procurement Notes

Verify that the specific suffix WH-Q matches the required tape and reel configuration for automated assembly processes. Confirm that the AEC-Q101 qualification status aligns with the target automotive application requirements. Ensure the DFN-6 footprint dimensions are compatible with the PCB layout constraints before finalizing procurement orders.

Surge Suppression ICS Selection Notes

Select this component when dual-directional surge suppression is required for sensitive circuits operating up to 550V. The low capacitance profile makes it suitable for high-speed data lines where signal distortion must be minimized. Consider the 100mA current rating to ensure adequate protection against transient events without interfering with normal operation.

Surge Suppression ICS Part Context

This part belongs to the TBU-DB-Q series, which focuses on dual bidirectional protection solutions. Unlike single-channel protectors, this device handles surges on multiple lines simultaneously. The series is designed to meet stringent automotive standards, offering robust performance in harsh electrical environments while maintaining a compact form factor.

Surge Suppression ICS Replacement Considerations

Direct substitutes within the same series include variants with different voltage or current ratings, such as the TBU-CA065-100-WH-Q. Verify that any replacement maintains the DFN-6 package and bidirectional functionality to ensure mechanical and electrical compatibility.
