Procurement Notes

Verify the specific datasheet version and package variant when ordering. Confirm that the selected packaging format matches production requirements. Ensure compatibility with existing thermal management strategies due to the operating temperature range. Check for any recent product change notices regarding assembly or material composition updates before finalizing procurement plans.

Selection Notes

Select this component for applications requiring robust surge suppression on data lines. The dual bidirectional nature suits differential signaling environments. Consider the low capacitance characteristic for high-speed data transmission integrity. Evaluate the 100 mA current rating against peak load requirements. Ensure the DFN package dimensions fit the designated PCB footprint constraints.

Part Context

This part belongs to the TBU-PK Series of Bourns Transient Blocking Units. These devices are engineered as electronic current limiters offering fast response times. The series provides protection against electrical overstress events. The PK designation indicates specific impedance characteristics within the broader TBU product family.

Replacement Considerations

The TBU-PL050-100-WH is listed as a discontinued alternative with available stock. Verify impedance differences between the PL and PK series variants before substitution. Ensure pinout and package dimensions remain compatible with the original design.
