Bourns® Model P500-G and P850-G Series  
TBU® HSPs are not recommended for POTS  
applications. This series is suited for  
Features  
Extremely high speed performance  
Blocks high voltages and currents  
Two TBU® protectors in one small package  
Simple, superior circuit protection  
Minimal PCB area  
applications requiring a dual bidirectional device  
where 50 ohms of series resistance is acceptable.  
For new SLIC applications, we recommend that  
customers evaluate our TBU-PL Series.  
RoHS compliant*, UL Recognized  
P500-G and P850-G Series Dual TBU® High-Speed Protectors

Bourns Model P500-G and P850-G TBU products are dual  
high-speed bidirectional protection components, constructed  
using MOSFET semiconductor technology, designed to protect  
against faults caused by short circuits, AC power cross,  
induction and lightning surges.

The TBU high speed protector, triggering as a function of  
Telcordia  
ITU-T  
GR-1089  
the MOSFET, blocks surges and provides an effective barrier  
behind which sensitive electronics are not 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.
