IP4234CZ6

IP4234CZ6 Single USB 2.0 ESD protection to IEC 61000-4-2 level 4 Rev. 01 — 16 April 2009 Product data sheet 1. Product profile 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 π-filter 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 π-filter ESD protection diodes plus a Zener diode in a miniature 6-lead SOT457 package. 1.2 Features I Pb-free and RoHS compliant I Simple, direct signal routing provides for high speed signal integrity I ESD protection compliant to IEC 61000-4-2 level 4, ±8 kV contact discharge I Significant reduction in peak clamping and peak residual current I Four low input capacitance (2.0 pF 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) compliant 1.3 Applications I General-purpose downstream ESD protection high frequency analog signals and high-speed serial data transmission for ports inside: N C...
