TBU-CA065-100-WH

Overview

The Bourns TBU-CA065-100-WH is a board-mounted surge protector classified as a bidirectional Transient Blocking Unit (TBU). It utilizes MOSFET technology to provide integrated overcurrent and overvoltage protection. The device features a DFN surface-mount package with SMD/SMT termination. Key electrical ratings include a voltage rating of 650 V and a current rating of 100 mA. It operates within a temperature range from -55 °C to +125 °C.

Feature Summary

Bidirectional transient blocking capability for versatile circuit integration
Integrated overcurrent and overvoltage protection mechanisms
Automatic reset functionality upon removal of the fault condition

Applications

Video transcoder circuit protection
RS-485 interface protection
RS-422 interface protection

Procurement Notes

Verify the specific suffix WH against the manufacturer datasheet to confirm packaging configuration and compliance status. Ensure the bidirectional characteristic aligns with the signal polarity requirements of the target application. Cross-reference the DFN footprint dimensions with the PCB layout library prior to finalizing the design.

Selection Notes

Select this component when bidirectional protection is required for high-speed data lines sensitive to electrostatic discharge or lightning-induced surges. The low capacitance inherent to the TBU architecture preserves signal integrity in high-bandwidth applications. Verify that the system's normal operating voltage remains below the device's breakdown threshold to ensure proper standby operation.

Part Context

This part belongs to the TBU family of high-speed protectors developed by Bourns. These devices function as electronic current limiters, offering superior performance compared to traditional fuses or TVS diodes by actively blocking energy rather than shunting it. The series is widely utilized in industrial control and communication ports requiring robust transient immunity.
