Overview
The SZESD7205WTT1G is a low capacitance ESD protection diode designed by onsemi to protect high-speed data lines from electrostatic discharge (ESD). This device is particularly suited for applications requiring ultra-low capacitance and low ESD clamping voltage, making it an ideal solution for protecting voltage-sensitive high-speed data lines. The small form factor and flow-through style package facilitate easy PCB layout and maintain consistent impedance between high-speed differential lines such as Ethernet and LVDS, commonly found in automotive camera modules.
