Description  
products are low capacitance dual bidirec-  
tional high-speed protection components,  
constructed using MOSFET semiconductor  
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 reflow profiles.
