TBU-DT065-100-WH

Overview

The Bourns TBU-DT065-100-WH is a board mount surge protector classified as a dual unidirectional TBU device. It operates with a voltage rating of 300 V and a current rating of 100 mA. The component utilizes SMD/SMT termination types within a DFN package. Its operational temperature range spans from -40 C to +85 C. Key features include overcurrent and overvoltage protection capabilities. The device is UL compliant and RoHS detailed.

Feature Summary

• Dual unidirectional configuration for circuit protection
• Solid-state resettable silicon technology
• Integrated overcurrent and overvoltage suppression

Applications

• Ethernet ports
• Protection modules and dongles
• Test equipment

Procurement Notes

Verify the specific datasheet version when sourcing, as manufacturing sites or marking changes may occur via Product Change Notifications. Confirm that the DFN package dimensions align with the target PCB footprint. Ensure the 300 V rating matches the system requirements, distinguishing it from other variants in the series with different voltage thresholds.

Selection Notes

Select this part for applications requiring dual unidirectional protection with a 300 V threshold. Compare against the TBU-DT065-200-WH if higher current handling is needed. Consider the TBU-CA series for bidirectional requirements. Verify thermal management needs within the specified operating temperature range during design integration.

Part Context

This component belongs to the TBU-DT series of high-speed protectors from Bourns. These devices function as electronic crowbar fuses (ECL) to block transient currents. The series provides voltage isolation and surge protection against lightning or power induction events.
