AR3304S8
4-Line TVS for Ethernet Interfaces
Description
Mechanical Characteristics
Package: SO-8
The AR3304S8 is a low capacitance high power TVS,
utilizing leading monolithic silicon technology to provide
fast response time and low ESD clamping voltage, mak-
ing this device an ideal solution for protecting voltage
sensitive high-speed data lines. The AR3304S8 complies
with the IEC 61000-4-2 (ESD) with ±30kV air and ±30kV
contact discharge. Each device will protect two line pairs
high-speed lines. The combination of small size, low ca-
pacitance, and high surge capability makes them ideal for
use in applications such as Gigabit Ethernet, telecommu-
nication lines, and LVDS interfaces.
