IP4234CZ6 Datasheet | NXP Semiconductors

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 Electro Static Discharge (ESD). The π-filter structure is implemented with a small series resistor to provide the necessary protection to signal and supply ponents from ESD voltages greater than ±8 k V 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 π-filter ESD protection diodes plus a Zener diode in a miniature 6-lead SOT457 package. 1.2 Features I Pb-free and Ro HS pliant I Simple, direct signal routing provides for high speed signal integrity I ESD protection pliant to IEC 61000-4-2 level 4, ±8 k V contact discharge I Significant reduction in peak clamping and peak residual current I Four low input capacitance (2.0 p F typical) rail-to-rail ESD protection diodes I Low voltage clamping due to an integrated Zener diode I Small 6-lead SO6 (SOT457) package I IEC 61000-4-5 15 A Lightning (8/20 µs) pliant 1.3 Applications I General-purpose downstream ESD protection high frequency analog signals and high-speed serial data transmission for ports inside: N Cellular and PCS mobile handsets N PC/Notebook USB2.0/IEEE1394 ports N DVI interfaces N HDMI interfaces N Cordless telephones N Wireless data (WAN/LAN) systems N PDAs NXP Semiconductors Single USB 2.0 ESD protection to IEC 61000-4-2 level 4 2.
