TBU-DT Series - TBU® High Speed Protectors  
General Information  
The TBU-DT Series of Bourns® TBU® (Transient Blocking Unit) products are very low  
capacitance dual unidirectional high speed surge protection components designed to  
protect against faults caused by short circuits, AC power cross, induction and lightning  
surges.

The TBU-DT series 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, and Pin 4 is positive with respect to Pin 3.  
No current limiting exists in the opposite polarity, and the TBU® device appears as resis-  
tive 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.

TBU® Device  
The TBU® protector blocks surges and provides an effective barrier behind which sensi-  
tive 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 bias  
Agency Approval  
reset  
or have DC bias below Vreset (such as unpowered signal lines).  
Description  
File Number: E315805  
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.
