1.1 General description

The IP4220CZ6 is designed to protect I/O lines sensitive to capacitive load, such as

USB 2.0, ethernet, Digital Video Interface (DVI) and so on, from damage due to

ElectroStatic Discharge (ESD). It incorporates four pairs of ultra low capacitance rail-to-rail

ESD protection diodes plus a Zener diode to provide protection to signal and supply

components from ESD voltages up to 8 kV contact discharge. Protection is supply

voltage independent due to the rail-to-rail diodes being connected to the Zener diode.

The device is encapsulated in a small 6-lead SOT457 (SC-74) Surface-Mounted

Device (SMD) plastic package.

1.2 Features and benefits

 Pb-free, Restriction of Hazardous Substances (RoHS) compliant and free of halogen

and antimony (Dark Green compliant)

 ESD protection up to 8 kV contact discharge; IEC 61000-4-2, level 4 compliant

 Four pairs of ultra low input capacitance (CI = 1 pF) ESD rail-to-rail protection diodes

 Low voltage clamping due to integrated Zener diode

 Small 6-lead TSOP6 (SOT457) SMD package

1.3 Applications

 General-purpose downstream ESD protection for high-frequency analog signal ports

and high-speed serial data transmission ports in:

 Cellular phone and Personal Communication System (PCS) mobile handsets

 PC/notebook USB 2.0/IEEE1394 ports

 DVI

 Cordless telephones

 Wireless data (WAN/LAN) systems

 Mobile Internet Devices (MID)

 Portable media Players (PMP)

 High-Definition Multimedia Interface (HDMI)
