The ESDS552 is a diode type TVS that provides a path to ground for dissipating transient voltage spikes, such as ESD or surge, on signal lines and power lines. Connect the device in parallel to the down stream circuitry for protection. As the current from the transient passes through the device, only a small voltage drop is present across the diode. This is the voltage presented to the protected IC. The low R_DYN of the triggered TVS holds this voltage (V_CLAMP) to a safe level for the protected IC. For more information on how to properly use this device, refer to the ESD Packaging and Layout Guide for details.
