The TESD15G2U is designed to provide robust ESD protection, typically exceeding industry standards such as IEC 61000-4-2. It features a low clamping voltage, which limits the maximum voltage seen by the protected device during an ESD event. The fast response time ensures that the TVS diode quickly diverts the ESD current away from the protected device, minimizing the stress on the device. The low capacitance is crucial for protecting high-speed data lines, such as USB and HDMI, where excessive capacitance can degrade signal integrity.

This TVS diode is typically connected between the signal line and ground, providing a low-impedance path for ESD currents to flow to ground. When an ESD event occurs, the TVS diode quickly turns on and clamps the voltage to a safe level, protecting the downstream components from damage. The specific clamping voltage and capacitance values will vary depending on the specific model and manufacturer's specifications.
