Overview
The TBU-KE040-100-WH is a board mount surge protector from Bourns Inc., designed for transient voltage suppression. It features a working voltage of 200V and a clamping voltage of 400V. The component supports a current rating of 100mA and contains one circuit. It is housed in a surface-mount DFN package, specifically a 2-DFN (2.5x5) configuration with an exposed pad, ensuring reliable integration into compact electronic designs.
Feature Summary
- Provides high-speed transient blocking unit protection against voltage surges
- Utilizes a low-profile surface-mount DFN package for space-constrained applications
- Functions as a unidirectional surge suppression device for circuit integrity
Applications
- General purpose circuit protection
- Surge suppression IC applications
- Board mount transient voltage protection
Procurement Notes
Verify the specific suffix 'WH' against the manufacturer's official documentation to confirm exact packaging and tape/reel specifications. Ensure the selected variant matches the required 2-DFN footprint and pin configuration for your PCB layout. Cross-reference the 200V working voltage and 400V clamping parameters with your system's electrical requirements before procurement.
Selection Notes
Select this component when a unidirectional, high-speed surge protector is required for general-purpose applications. The 200V working voltage defines its operational limit, while the 100mA rating indicates its current handling capability. Consider the 2-DFN package dimensions for mechanical fitment and ensure the single-circuit design aligns with the protection needs of the target signal or power line.
Part Context
This part belongs to the TBU-KE Series of Transient Blocking Units by Bourns Inc. These components are categorized under Circuit Protection and Surge Suppression ICs. The series is engineered to offer robust protection against transient events, distinguishing itself through high-speed response capabilities compared to standard suppressors.
Replacement Considerations
Consult the TBU-(DT,KE) Series Bulletin for officially documented substitute part numbers within the same family. Verify compatibility regarding voltage ratings, package type, and circuit count before substituting.
