1.1 General description

The PRTR5V0U8S is designed to protect Input/Output (I/O) ports that are sensitive

concerning capacitive load, such as USB 2.0, Ethernet, Digital Video Interface (DVI), etc.

from destruction by ElectroStatic Discharges (ESD).

Therefore, the PRTR5V0U8S incorporates eight pairs of ultra low capacity rail-to-rail

diodes plus an additional Zener diode to provide protection to downstream signal and

supply components from ESD voltages as high as ±8 kV contact discharge.

Due to the rail-to-rail diodes being connected to the Zener diode, the protection is working

independently from the availability of a supply voltage.

The PRTR5V0U8S is fabricated using thin film-on-silicon technology and integrates eight

pairs of ultra low capacity rail-to-rail ESD protection diodes in a miniature 10-lead

TSSOP10 package.
