ACE00581A

Ultra Low Capacitance 4 -Line ESD Protection Array

VER 1.1

Description

The ACE00581A is 4-channel very low capacitance ESD transient voltage suppressor which provides

a very high level of protection for sensitive electronic components that may be subjected to electrostatic

discharge. It is particularly well-suited to protect systems with high speed communication lines from ESD,

EFT, and lighting.

The ACE00581A consists of eight low capacitance steering diodes and a TVS diode in a SLP package.

Each channel of ACE00581A could safely dissipate ESD strikes of ±15KV air discharge as well as ±8KV

contact discharge, meeting the requirement of the IEC 61000-4-2 international standard. Using the

MIL-STD-883 (Method 3015) specification for Human Body Model (HBM) ESD, the device provides

protection for contact discharges to greater than ±8KV.
