The TBU (transient-blocking-unit) DT-series circuit-protection devices tolerate ac-mains-power contact without circuit damage. The electronic current limiters provide protection against faults from short circuits, ac-power cross, induction, and lightning surges. The fast-reacting protectors do not alter the signal performance of high-speed communication ports, unlike high-capacitance protectors. The devices target use in outdoor applications, such as security systems, photovoltaic panels, and service kiosks. The series includes eight models offering continuous ac-voltage ratings as high as 425V rms and nominal trigger currents of 150 to 750 mA. The devices come in surface-mount DFN packages. The TBU-DT-065 and TBU-DT-085-XXX-WH sell for 69 cents each (15,000).
