The TPD4S009 and TPD4S010 are four-channel TVS diode arrays for electrostatic discharge (ESD) protection. TPD4S009 and TPD4S010 are rated to dissipate contact ESD strikes at the maximum level specified in the IEC 61000-4-2 international standard (Level 4), with ±8-kV contact discharge ESD protection. The low capacitance (0.8-pF) of these devices, coupled with the excellent matching between differential signal pairs (0.05-pF line-line capacitance for the TPD4S009DRY) enables this device to provide transient voltage suppression circuit protection for high-speed differential data rates (3-dB bandwidth > 4 GHz).
