The ESD2CANxx24-Q1 is a dual channel TVS diode which is used to provide a path to ground for dissipating ESD events on differential CAN signal lines. The CAN signal lines are typically routed throughout the automobile to connect between the different ECUs. 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 R_DYN of the triggered TVS holds this voltage, V_CLAMP, to a safe level for the protected IC.
