The SP5003 Series Transient Voltage Suppression (TVS) Diode from Littelfuse is a highly integrated Common-Mode Filter (CMF) that provides both electrostatic discharge (ESD) protection and common-mode EMI filtering for systems that use high speed differential serial interfaces. Its high common-mode stop band attenuation in the cellular frequency ranges effectively prevents high speed data lines from interfering with radio frequencies. The SP5003 Series can protect and filter two differential line pairs. Its low-profile RoHS-compliant TDFN-10 package and compact design offer substantial cost and space savings over discrete solutions.
