TBU-CX Series - TBU ? High-Speed Protectors
General Information
Agency Approval
The TBU-CX Series of Bourns ? TBU ?
products are low capacitance dual bidirec-
tional high-speed protection components,

technology, and designed to protect against
faults caused by short circuits, AC power cross,
induction and lightning surges.
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 re?ow pro?les.
