■ Two TBU^® protectors in one small package
■ Simple, superior circuit protection
■ Minimal PCB area
■ RoHS compliant*, UL Recognized
Bourns^® Model P500-G and P850-G Series
TBU^® HSPs are not recommended for POTS
applications. This series is suited for
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.
P500-G and P850-G Series Dual TBU^® High-Speed Protectors
Transient Blocking Units - TBU^® Devices
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
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.
