IP4234CZ6

Single USB 2.0 ESD protection to IEC 61000-4-2 level 4

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.

Features

  • Pb-free and RoHS compliant
  • Simple, direct signal routing provides for high speed signal integrity
  • ESD protection compliant to IEC 61000-4-2 level 4, +-8 kV contact discharge
  • Significant reduction in peak clamping and peak residual current
  • Four low input capacitance (2.0 pF typical) rail-to-rail ESD protection diodes
  • Low voltage clamping due to an integrated Zener diode
  • Small 6-lead SO6 (SOT457) package
  • IEC 61000-4-5 15 A Lightning (8/20 us) compliant

Target applications

  • General-purpose downstream ESD protection high frequency analog signals and high-speed serial data transmission for ports inside:
    • Cellular and PCS mobile handsets
    • PC/Notebook USB2.0/IEEE1394 ports
    • DVI interfaces
    • HDMI interfaces
    • Cordless telephones
    • Wireless data (WAN/LAN) systems
    • PDAs
