CM1293

2, 4, and 8-Channel Low Capacitance ESD Protection Arrays

Features

Product Description

•

2, 4, and 8 channels of ESD protection

Provides ESD protection to IEC61000-4-2

- 8kV contact discharge

- 15kV air 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 SOT, and MSOP packages

Lead-free version available

The CM1293 family of diode arrays has been designed

to provide ESD protection for electronic components or

sub-systems 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 which steer the positive or neg-

•

ative ESD current pulse to either the positive (V ) or

negative (V ) supply rail. A Zener diode is embedded

•

between V and V , offering two advantages. First, it

protects the V rail against ESD strikes, and second,

it eliminates the need for a bypass capacitor that would

otherwise be needed for absorbing positive ESD

strikes to ground. The CM1293 will protect against

ESD pulses up to ( 15kV air, 8kV contact discharge)

per the IEC 61000-4-2 Level 4 standard.

Applications

•

DVI ports, HDMI ports in notebooks, set top boxes,

digital TVs, LCD displays

Serial ATA ports in desktop PCs and hard disk

drives

PCI Express ports

General purpose high-speed data line ESD

protection

This device is particularly well-suited for protecting sys-

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

^{IEEE1394 (Firewire}®, iLink™), Serial ATA, DVI, 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 CM1293 family of devices is available with

optional lead-free finishing.
