TBU-CA Series - TBU® High-Speed Protectors
General Information
The TBU-CA Series of Bourns® TBU® products are low capacitance single bidirectional high-speed protection
Line In/ Line Out
components, constructed using MOSFET
semiconductor technology, and designed
to protect against faults caused by short
circuits, AC power cross, induction and lightning surges.
Line Out/ Line In
TBU® Device
The TBU® high-speed protector placed in the system circuit will monitor the current with the MOSFET detection circuit triggering to provide an effective barrier behind which sensitive electronics will not be exposed to large voltages or currents during surge events. The TBU® device is provided in a surface mount DFN package and meets industry standard requirements such as RoHS and Pb Free solder reflow profiles.
