TBU-KE Series - TBU® High Speed Protectors  
General Information

UL  
File Number: E315805  
surge protection components designed to protect  
against faults caused by short circuits, AC  
power cross, induction and lightning surges.  
TBU® Device  
The TBU-KE is a unidirectional TBU® device: the TBU® protector will trip in less than  
1 μs when the current reaches the maximum value in one direction only, that is when  
Pin 1 is positive in voltage with respect to Pin 2. No current limiting exists in the oppo-  
site polarity, and the TBU® protector appears as resistive in nature. The reverse current  
should not exceed the maximum trip current level of the TBU® device. An external  
diode may be used to prevent reverse current in DC biased applications.  
The TBU® protector blocks surges and provides an effective barrier behind which sen-  
sitive electronics will not be exposed to large voltages or currents during surge events.  
After the surge, the TBU® device resets when the voltage across the TBU® device falls  
to the V  
level. The TBU® device will automatically reset on lines which have no DC  
reset  
bias or have DC bias below V  
(such as unpowered signal lines).  
reset  
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.
