Additional Details:

The ECLAMP2357NQ.TCT is typically connected between the protected data line and ground. It operates by clamping the voltage during a transient event, diverting the excess energy away from the sensitive components. The specific clamping voltage and capacitance values are detailed in the product datasheet. It is important to select a TVS diode array with appropriate specifications for the specific application and the expected transient threat levels. The device is available in a DFN package.
