validate and test their design implementation to confirm system functionality.

9.1 Application Information

TPD2E2U06 is a diode type TVS which is typically used to provide a path to ground for dissipating ESD events

on hi-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
