TBU-RS055-300-WH

Overview

The Bourns TBU-RS055-300-WH is a dual-channel transient voltage suppressor designed for RS-485 communication interfaces. It integrates overcurrent and overvoltage protection within a single compact package, featuring a maximum pulse voltage of 550 V and a maximum RMS voltage of 250 V. The device provides fast protection with a reaction time of 1 µs, ensuring compliance with IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (surge) standards.

Feature Summary

Integrates dual-channel transient voltage suppression and overcurrent protection into a single component
Provides rapid response capability to mitigate high-energy transients effectively
Reduces circuit board space requirements significantly compared to discrete protection solutions

Applications

RS-485 interface surge protection
AISG (Antenna Interface Standards Group) modem protection
Industrial communication port protection

Procurement Notes

Verify the specific datasheet version and manufacturing site status before procurement, as product change notifications may affect silicon sourcing. Confirm that the ordering suffix corresponds to the required packaging format. Ensure compatibility with system voltage levels and check for any recent RoHS compliance updates or material declarations.

Selection Notes

Select this component when designing circuits requiring integrated protection for differential data lines in industrial environments. It serves as an alternative to discrete TVS and fuse combinations, offering a smaller footprint. Consider pairing it with primary surge arresters like gas discharge tubes for comprehensive multi-stage protection schemes.

Part Context

This part belongs to the TBU-RS Dual Channel TBU High-Speed Protector Series by Bourns. These devices are engineered specifically for high-speed data interfaces, combining the functions of a transient voltage suppressor and a resettable fuse to protect sensitive electronics from electrical overstress events.
