The TSM24A-Q1 is a TVS diode 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 TVS, only a small voltage drop is present across the diode. The small voltage drop is 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.
