TBU-DF Series - TBU® High-Speed Protectors  
General Information  
The TBU-DF Series of Bourns® TBU® products are low capacitance dual bidirectional high-speed Electronic  
Current Limiters (ECLs), constructed using MOSFET semiconductor technology, and designed to protect  
against faults caused by short circuits, overvoltage transients and faults in battery cells, up to rated limits.

Line 1 I/O  
Line 2 I/O  
The TBU® high-speed protector placed in the system circuit will monitor the current with the MOSFET detec-  
tion circuit triggering to provide an effective barrier behind which sensitive electronics will not be exposed to  
large voltages or currents during transient events.  
®
TBU Device  
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.
