Integrated quad ultra-low capacitance ESD protection

The PRTR5V0U4Y is designed to protect Input/Output (I/O) ports that are sensitive to capacitive load, such as USB 2.0, Ethernet and DVI from destruction by ElectroStatic Discharge (ESD). It provides protection to downstream signal and supply components from ESD voltages as high as +-8 kV (contact discharge).

The PRTR5V0U4Y incorporates four pairs of ultra-low capacitance rail-to-rail diodes plus a Zener diode. The rail-to-rail diodes are connected to the Zener diode which allows ESD protection to be independent of supply voltage. The PRTR5V0U4Y is fabricated using thin film-on-silicon technology integrating four ultra-low capacitance rail-to-rail ESD protection diodes in a miniature 6-lead SOT363 package.
