The maximum voltage rating of the TBU® device should never be exceeded. Where necessary, an OVP should be employed to limit the maximum voltage. A cost- effective protection solution combines Bourns® TBU® protection devices with a pair of Bourns® MOVs. For bandwidth sensitive applications, a Bourns® GDT may be substituted for the MOV. The TBU® device, constructed using MOSFET semiconductor technology, placed in the system circuit will monitor the current with the MOSFET detection circuit triggering to provide an effective barrier behind which sensitive electronics are not exposed to large voltages or currents during surge events. The TBU® device operates in approximately 1 μs - once line current exceeds the TBU® device’s trigger current Itrigger. When operat- ed, the TBU® device will limit the current to less than the Itrigger value within the tblock duration. If voltage above Vreset is contin- uously sustained, the TBU® device will subsequently reduce the current to a quiescent current level within a period of time that is dependent upon the applied voltage. After the surge, the TBU® device resets when the voltage across the TBU® device falls to the Vreset level. The TBU® device will automatically reset on lines which have no DC bias or have DC bias below Vreset (such as unpowered signal lines). If the line has a normal DC bias above Vreset, the voltage across the TBU® device may not fall below Vreset after the surge. In such cases, special care needs to be taken to ensure that the TBU ® device will reset, with software monitoring as one method used to accomplish this. Bourns application engineers can provide further assistance. Basic TBU Operation Performance Graphs Typical V-I Characteristics (TBU-CA050-300-WH) Typical Trigger Current vs. Temperature Equip.

TBU-CA Series - TBU® High-Speed Protectors Product Dimensions DIMENSIONS: MM (INCHES) Recommended Pad Layout TBU® High-Speed Protectors have a 100 % matte-tin termination finish. For improved thermal dissipation, the recommended layout uses PCB copper areas which extend beyond the exposed solder pad. The exposed solder pads should be defined by a solder mask which matches the pad layout of the TBU ® device in size and spac- ing. It is recommended that they should be the same dimension as the TBU ® pads but if smaller solder pads are used, they should be centered on the TBU® package terminal pads and not more than Solder pad areas should not be larger than the TBU ® pad sizes to ensure adequate clearance is maintained. The recommended opening size 0.025 mm (0.0010 in.) less than the solder pad size. Extended copper areas beyond the solder pad significantly improve the junction to ambient thermal resistance, resulting in operation at lower junction temperatures with a corresponding benefit of reli- ability. All pads should soldered to the PCB, including pads marked as NC or NU but no electrical connection should be made to these pads. For minimum parasitic capacitance, it is recommended that signal, ground or power signals are not routed beneath any pad.
