The TPD2E009 device is a diode-array type TVS typically used to provide a path to ground for dissipating ESD events on high-speed signal lines between a human-interface connector and a system. As the current from ESD passes through the TVS, only a small voltage drop is present across the diode. This is the voltage presented to the protected IC. The low RDYN of the triggered TVS holds this voltage, VCLAMP, to a tolerable level to the protected IC.
