4-Channel Low Capacitance ESD

Protection Arrays

CM1225

Features

Product Description

•

Four channels of ESD protection

Provides ESD protection to IEC61000-4-2 Level 4

The CM1225 diode array has been designed to provide

ESD protection for electronic components or

subsystems requiring minimal capacitive loading. This

device is 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 negative ESD

current pulse to the ground pins (V_N). A Zener diode is

embedded between the positive terminal of the diode

pair to the ground. This eliminates the need for an

external bypass capacitor to absorb positive ESD strikes

to ground. The CM1225 protects against ESD pulses up

to 8kV per the IEC 61000-4-2 standard.

•

8kV contact discharge

•

Low channel input capacitance of 0.8pF (typically)

Channel input capacitance matching (I/O to I/O) of

0.02pF (typically) is ideal for differential signals

Minimal capacitance change for temperature and

voltage

•

Zener diode eliminates the need for external bypass

capacitors

•

Each I/O pin can withstand over 1000 ESD strikes*

Available in a RoHS compliant (lead-free) package

The CM1225 is particularly well-suited for protecting

systems using high-speed ports such as HDMI, DVI,

display, MDDI, USB 2.0, Serial ATA, IEEE1394

(FireWire and i.LINK), 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.

Applications

•

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

digital TVs, and LCD displays

Display and MDDI ports

•

Serial ATA ports in desktop PCs and hard disk

drives

•

PCI Express ports

USB2.0 ports at 480Mbps in desktop PCs,

notebooks and peripherals

The CM1225 is available in a RoHS-compliant, uUDFN

10-pin package.

•

IEEE1394 FireWire ports at 400Mbps / 800Mbps

General purpose high-speed data line ESD

protection

•

Protection of interface ports or IC pins which are

exposed to high ESD levels

*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.
