Surge Suppression ICS Procurement Notes

Verify the specific datasheet version and application notes for RS-485/RS-422 designs when sourcing. Confirm the 6-DFN footprint dimensions (6.5x5.5 mm) match the PCB layout requirements. Ensure the peak impulse voltage rating aligns with the system's transient environment specifications before finalizing procurement.

Surge Suppression ICS Selection Notes

Select this component for applications requiring dual-channel protection in a compact surface-mount form factor. Consider the 550V to 850V peak impulse voltage range relative to the system's operating voltage and expected surge levels. Evaluate the internal switch technology benefits for high-speed data line protection scenarios.

Surge Suppression ICS Part Context

This part belongs to the TBU-DF series of dual-channel high-speed protectors by Bourns. These devices are engineered to provide robust circuit protection while maintaining signal integrity. The series utilizes internal switch technology to manage overvoltage and surge events effectively across various industrial and communication applications.

Surge Suppression ICS Replacement Considerations

Check for other TBU-DF series variants with different peak impulse voltage ratings if the 550V-850V range does not suit the application. Verify pin compatibility and package dimensions when considering alternative surge protection ICs from Bourns or other manufacturers.
