1. Product pro?le

1.1 General description

The PRTR5V0U4AD 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). It provides protection to downstream

signal and supply components from ESD voltages as high as ± 8 kV (contact discharge).

The PRTR5V0U4AD incorporates four pairs of ultra-low capacitance rail-to-rail diodes

plus an additional Zener diode. The rail-to-rail diodes are connected to the Zener diode

which allows ESD protection to be independent of the availability of a supply voltage.

The PRTR5V0U4AD is fabricated using thin ?lm-on-silicon technology integrating four

ultra-low capacitance rail-to-rail ESD protection diodes in a miniature 6-lead SOT457

package.

1.2 Features

ESD protection compliant to IEC 61000-4-2 level 4, ± 8 kV contact discharge

Low voltage clamping due to integrated Zener diode

Four ultra-low input capacitance (1 pF typical) rail-to-rail ESD protection diodes

Small 6-lead SOT457 package

1.3 Applications

I General-purpose downstream ESD protection of high frequency analog signals and

high-speed serial data transmission for ports inside:

N Cellular mobile handsets

N USB 2.0 and IEEE 1394 ports in PC or notebook

N Interfaces: DVI and High De?nition Multimedia Interface (HDMI)

N Cordless telephones

N Wireless data systems: Wide Area Network (WAN) and Local Area Network (LAN)

N Personal Digital Assistants (PDAs)
