Two series of TVS diode arrays (SPA® diodes) from Littelfuse safeguard high-speed interfaces from damage due to electrostatic discharges (ESD). SP7538P series TVS diode arrays integrate eight channels of ultra-low capacitance rail-to-rail diodes and an additional Zener diode in a µDFN-9 package; SP0544T series TVS diode arrays have a similar design in a smaller µDFN-10, with four channels of ultra-low capacitance rail-to-rail diodes instead of eight. Both can safely absorb repetitive ESD strikes above the maximum level specified in the IEC61000-4-2 international standard (±8 kV contact discharge) without performance degradation. Their extremely low loading capacitance also makes them ideal for protecting high-speed signal pins.

Typical applications for both series include ESD protection for interfaces like V-By-One, Embedded DisplayPort, USB 2.0/3.0 ports, and HDMI, as well as flat panel displays, LCD/LED TVs, smartphones and mobile computing.
