Overview
The Bourns TBU-PL075-200-WH is a board mount surge protector from the TBU-PL series, designed for dual 50 ohm bidirectional applications. It functions as a silicon-based solid-state resettable device providing overcurrent and overvoltage protection. The component features an SMD/SMT DFN package with a rated current of 700 uA and operates within a temperature range of -55 C to +125 C.
Feature Summary
- Provides simultaneous overcurrent and overvoltage protection
- Acts as a solid-state resettable barrier against transient currents
- Designed for dual 50 ohm bidirectional signal lines
Applications
- Voice and VoIP slicer protection
- RS-485 port protection
- Data line surge suppression
Procurement Notes
Verify the specific datasheet for the TBU-PL075-200-WH to confirm exact electrical thresholds and thermal characteristics. Ensure compatibility with the target circuit's impedance requirements. Confirm that the DFN package footprint matches the PCB design specifications before finalizing procurement decisions.
Selection Notes
Select this component for applications requiring bidirectional protection on dual 50 ohm lines. Consider the 700 uA current rating and wide operating temperature range when evaluating environmental constraints. Compare against other TBU series variants like TBU-CA or TBU-RS if different trigger currents or form factors are required for the specific system architecture.
Part Context
This part belongs to the TBU-PL series of High-Speed Protectors (HSP) by Bourns. These devices utilize current limiting technology to block transient energy while maintaining normal operation. The series is distinct from automotive-certified AEC-Q101 variants, focusing instead on general industrial and telecommunications signal line protection standards.
Replacement Considerations
Consult official Bourns documentation for direct cross-reference equivalents. Verify that any substitute maintains the dual 50 ohm bidirectional specification and compatible DFN package dimensions to ensure mechanical and electrical interchangeability.
