TBU-PL Series is preferred.
TBU® P500-G and P850-G Protectors
Transient Blocking Units - TBU® Devices
Bourns® Model P500-G and P850-G TBU® products are 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
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
reï¬ow proï¬les.
