IP4234CZ6 Single USB 2.0 ESD protection to IEC 61000-4-2 level 4 Rev. 01 16 April 2009 Product data sheet 1. Product prole 1.1 General description The IP4234CZ6 is designed to protect Input/Output (I/O) USB 2.0 ports, that are sensitive to capacitive loads, from being damaged by ElectroStatic Discharge (ESD). The -lter structure is implemented with a small series resistor to provide the necessary protection to signal and supply components from ESD voltages greater than 8 kV contact discharge according IEC 61000-4-2, level 4. The ESD protection is independent of the supply voltage due to the rail-to-rail diode architecture being connected to a Zener diode. The IP4234CZ6 is fabricated using monolithic silicon technology and integrates two ultra-low capacitance -lter ESD protection diodes plus a Zener diode in a miniature 6-lead SOT457 package. 1.2 Features n Pb-free and RoHS compliant n Simple, direct signal routing provides for high speed signal integrity n ESD protection compliant to IEC 61000-4-2 level 4, 8 kV contact discharge n Signicant reduction in peak clamping and peak residual current n Four low input capacitance (2.0 pF typical) rail-to-rail ESD protection diodes n Low voltage clamping due to an integrated Zener diode n Small 6-lead SO6 (SOT457) package n IEC 61000-4-5 15 A Lightning (8/20 s) compliant 1.3 Applications n General-purpose downstream ESD protection high frequency analog signals and high-speed serial data transmission for ports inside: u Cellular and PCS mobile handsets u PC/Notebook USB2.0/IEEE1394 ports u DVI interfaces u HDMI interfaces u Cordless telephones u Wireless data (WAN/LAN) systems u PDAsIP4234CZ6 NXP Semiconductors Single USB 2.0 ESD protection to IEC 61000-4-2 level 4 2.
