C850

PL IA NT Features ■ Formerly CO M brand *R oH S ■ Extremely high speed performance ■ Blocks high voltages and currents ■ Very high bandwidth; GHz compatible ■ Small package, minimal PCB area ■ Simple, superior circuit protection ■ RoHS compliant*, UL Recognized The C650 & C850 Series are currently available, but not recommended for new designs. Bourns® TBU-CA Series is preferred. C650 and C850 Series TBU® High-Speed Protectors Transient Blocking Units - TBU® Devices Bourns® C650 and C850 series 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 reflow profiles.
