TBU-PL085-100-WH

Overview

The Bourns TBU-PL085-100-WH is a dual bi-directional transient voltage suppressor designed for board mount surge protection. It features an 850V rated voltage and a 100mA current rating, operating within a temperature range of -55°C to +125°C. The device utilizes a DFN surface-mount package and provides overcurrent and overvoltage protection. It is specifically engineered for voice and VoIP applications, offering high-speed performance and superior circuit protection against surges up to its rated limits.

Feature Summary

• Dual bi-directional configuration for comprehensive signal line protection
• Integrated overcurrent and overvoltage suppression capabilities
• High-speed performance suitable for sensitive communication interfaces

Applications

• Voice circuits
• VoIP lines
• Slic modules

Procurement Notes

Verify the specific suffix WH against the manufacturer's official datasheet to confirm package type and compliance status. Ensure the selected component matches the required 850V rating and 100mA current specifications for the target application. Cross-reference the DFN package dimensions with PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this component when dual-channel bidirectional protection is required for low-voltage signaling lines. The wide operating temperature range supports harsh environments. Consider the DFN footprint constraints during design. This part is distinct from unidirectional variants; verify polarity requirements against the system architecture to ensure correct signal integrity and protection coverage.

Part Context

This device belongs to the TBU series of transient voltage suppressors by Bourns Inc. These components are engineered to provide robust protection for electronic circuits against transient overvoltage events. The PL variant specifically addresses dual-line applications, distinguishing it from single-channel or unidirectional counterparts in the broader product family.

Replacement Considerations

TBU-PL085-200-WH offers identical voltage ratings but higher current capacity (200mA). Verify if the increased current handling meets system requirements without compromising protection thresholds.
