Features Bourns Model P850-G Series TBU HSPs are not recommended for POTS Extremely high speed performance applications. This series is suited for applications requiring a dual bidirectional device Blocks high voltages and currents where 50 ohms of series resistance is acceptable. For new SLIC applications, we recommend that Two TBU protectors in one small package customers evaluate our TBU-PL Series. Simple, superior circuit protection Minimal PCB area RoHS compliant*, UL Recognized P850-G Series Dual TBU High-Speed Protectors Transient Blocking Units - TBU Devices Agency Approval Bourns Model P850-G TBU products are dual high-speed UL recognized component File E315805. bidirectional protection components, constructed using MOSFET semiconductor technology, designed to protect against faults caused by short circuits, AC power cross, Industry Standards induction and lightning surges. Description Model The TBU high speed protector, triggering as a function of Telcordia GR-1089 Port Type 3, 5 P850-G the MOSFET, blocks surges and provides an effective barrier ITU-T K.20, K.20E, K.21, K.21E, K.45 P850-G 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 re ow pro les.
