*RoHS COMPLIANT eatures Extremely high speed performance Blocks high voltages and currents Two TBU protectors in one small package Simple, superior circuit protection Minimal PCB area RoHS compliant*, UL Recognized Bourns Model 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. or new SLIC applications, we recommend that customers evaluate our TBU-PL Series. P850-G Series ual TBU High-Speed Protectors Transient Blocking Units - TBU evices Bourns Model P850-G TBU products are dual high-speed bidirectional protection components, constructed using MOSET 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 MOSET, 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 N package and meets industry standard requirements such as RoHS and Pb ree solder refl ow profi les.
