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

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.
