TBU-CA065-200-WH

Overview

The Bourns TBU-CA065-200-WH is a board-mount surge protector classified as a bidirectional Transient Breakdown Unit (TBU). It features a DFN surface-mount package with dimensions of 6.5mm length, 4mm width, and 0.85mm height. The device has a maximum reverse standoff voltage (Vwm) of 20V and a clamping voltage (VC) of 650V. It supports a maximum peak pulse current (Ippm) of 0.4A. The component operates within a temperature range of -55°C to +125°C and contains a single diode configuration.

Feature Summary

• Provides bidirectional protection against overcurrent and overvoltage transients
• Functions as a high-speed protector for sensitive circuit inputs
• Utilizes a compact DFN surface-mount package for space-constrained designs

Applications

• ESD protection for electronic interfaces
• Surge suppression in communication lines
• Protection of low-voltage signal paths from transient events

Procurement Notes

Verify the specific suffix WH against the manufacturer's official datasheet to confirm package variant and tape-and-reel specifications. Ensure the selected component matches the required bidirectional configuration and voltage ratings for the target application circuit. Cross-reference the RoHS compliance status and UL certification details with the latest product documentation before finalizing procurement orders.

Selection Notes

Select this component when bidirectional transient protection is required for low-voltage signals up to 20V. The 650V clamping voltage and 0.4A peak current rating define its surge handling capability. Consider the DFN footprint and operating temperature range of -55°C to +125°C for environmental compatibility. This device is suitable for applications needing integrated overcurrent and overvoltage suppression without shunting normal operation.

Part Context

This part belongs to the Bourns TBU series of board-mount surge protectors. These devices are designed to mitigate damaging transient surges, electrostatic discharge, and noise from surrounding equipment or dirty power sources. The series offers solutions that bring inputs to a safe level rather than completely shunting the circuit, thereby prolonging the life of electronics exposed to out-of-spec conditions.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source data. Verify functional equivalence by comparing bidirectional TVS characteristics, clamping voltage, and package dimensions if considering alternative manufacturers.
