IP4281CZ10

ESD protection for high-speed interfaces

Rev. 01 — 25 September 2008 Product data sheet

1. Product profile

1.1 General description

The IP4281CZ10 is designed for HDMI interface protection. The device includes
high-level ElectroStatic Discharge (ESD) protection diodes for the TMDS signal lines.

All TMDS intra-pairs are protected by a special diode configuration offering a low line
capacitance of only 0.7 pF. These diodes provide protection to downstream components
from ESD voltages up to ±8 kV contact according to IEC 61000-4-2, level 4.

1.2 Features

n Pb-free, RoHS compliant and free of Halogen and Antimony (dark green compliant)
n ESD protection for HDMI and other LVDS data lines
n All TMDS lines with integrated rail-to-rail clamping diodes for downstream ESD

protection of ±8 kV according to IEC61000-4-2, level 4

n Matched 0.5 mm trace spacing
n TMDS lines with ≤ 0.05 pF matching capacitance between TMDS pairs
n Line capacitance of only 0.7 pF for each channel
n 4-channel, 10-terminal Ultra-Thin Leadless Package (UTLP)
n HDMI 1.3a compliant

1.3 Applications

The IP4281CZ10 is designed for HDMI receiver and transmitter port protection:

n TV, monitor
n Notebook, main board graphics card and ports
n Set-top box and game consoles
n DVD recorder and player
