1. Product profile
1.1 General description
The IP4220CZ6 is designed to protect I/O lines sensitive to capacitive load, such as USB
2.0, ethernet, DVI etc. from damage due to ElectroStatic Discharge (ESD). It incorporates
four pairs of ultra-low capacitance rail-to-rail diodes plus an additional Zener diode to
provide protection to signal and supply components from ESD voltages as high as ±8kV
contact discharge. Protection is supply voltage independent due to the rail-to-rail diodes
being connected to the Zener diode. The IP4220CZ6 integrates four pairs of ultra-low
capacitance rail-to-rail ESD protection diodes in a miniature 6-lead SOT457 package.
1.2 Features
■ESD IEC 61000-4-2 level 4, ±8 kV contact discharge compliant protection
■Four pairs of ultra-low input capacitance (1 pF typ.) ESD rail-to-rail protection diodes
■Low voltage clamping due to integrated Zener diode
■Small 6 lead SO6 (SOT457) package
■IEC 61000-4-5 15A Lightning (8/20 µs)
1.3 Applications
■General-purpose downstream ESD protection for high frequency analog signal ports
and high-speed serial data transmission ports in:
◆Cellular and PCS mobile handsets
◆PC-/notebook USB 2.0/IEEE1394 ports
◆DVI interfaces
◆Cordless telephones
◆Wireless data (WAN/LAN) systems
◆PDAs
◆HDMI

7. Application information
7.1 Universal serial bus 2.0 protection
The IP4220CZ6 is optimized to protect, for example, two USB 2.0 ports from ESD. Each
device is capable of protecting both USB data lines and the VBUS supply. A typical
application is shown in Figure 1.
