2-and 4-Channel Low Capacitance

ESD Protection Arrays

CM1293A

Features

Product Description

•

Two and four channels of ESD protection

Provides ESD protection to IEC61000-4-2

The CM1293A family of diode arrays has been

designed to provide ESD protection for electronic

components or subsystems requiring minimal

capacitive loading. These devices are ideal for

protecting systems with high data and clock rates or

for circuits requiring low capacitive loading. Each

ESD channel consists of a pair of diodes in series

that steer the positive or negative ESD current pulse

to either the positive (V_P) or negative (V_N) supply rail.

A Zener diode is embedded between V_Pand V_Nwhich

helps protect the V_CCrail against ESD strikes. The

CM1293A protects against ESD pulses up to 8kV

contact discharge) per the IEC 61000-4-2 Level 4

standard.

•

8kV contact discharge

•

Low loading capacitance of 2.0pF max.

Low clamping voltage

Channel I/O to I/O capacitance 1.5pF typical

Zener diode protects supply rail and eliminates

the need for external by-pass capacitors

Each I/O pin can withstand over 1000 ESD

strikes*

•

Available in RoHS-compliant, lead-free SOT and

MSOP packages

Applications

•

DVI ports, HDMI ports in notebooks, set top

boxes, digital TVs, LCD displays

Serial ATA ports in desktop PCs and hard disk

drives

This device is particularly well-suited for protecting

systems using high-speed ports such as USB2.0,

•

IEEE1394 (Firewire, iLink), Serial ATA, DVI,

•

PCI Express ports

General purpose high-speed data line ESD

protection

HDMI, and corresponding ports in removable

storage, digital camcorders, DVD-RW drives and

other applications where extremely low loading

capacitance with ESD protection are required in a

small package footprint.

The CM1293A family of devices is available with

RoHS-compliant, lead-free finishing.

Block Diagram

*Standard test condition is IEC61000-4-2 level 4 test circuit with each pin subjected to 8kV contact discharge for 1000 pulses. Discharges are timed at 1 second intervals and all 1000 strikes are completed in one

continuous test run. The part is then subjected to standard production test to verify that all of the tested parameters are within spec after the 1000 strikes.
