Bourns® Model P650-U and P850-U products are high speed,  
unidirectional protection components, constructed using  
MOSFET semiconductor technology, designed to protect against  
faults caused by short circuits, AC power cross, induction and  
lightning surges.  
UL recognized component File # E315805.

P850-U  
Port Type 3, 5  
Telcordia GR-1089  
The TBUhigh speed protector, triggering as a function of 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 TBUdevice is provided in a  
surface mount DFN package and meets industry standard  
requirements such as RoHS and Pb Free solder reflow profiles.
