2, 4, and 8-Channel Low-Capacitance

ESD Protection Array

CM1230

Features

Product Description

•

Two, four, and eight channels of ESD protection

Provides ESD protection to IEC61000-4-2

Level 4

The CM1230 is a family of 2, 4 and 8 channel, very

low capacitance ESD protection diode arrays in a

CSP form factor. It is ideal for protecting systems

with high data and clock rates or for circuits that

need low capacitive loading. Each channel consists

of a pair of ESD diodes that act as clamp diodes to

steer ESD current pulses to either the positive or

negative supply rail. A zener diode is integrated

between the positive and negative supply rails. The

•

8kV contact discharge

•

15kV air discharge

•

Low loading capacitance of 0.8pF typical

Minimal capacitance change with temperature

and voltage

Channel I/O to GND capacitance difference of

0.02pF typical is ideal for differential signals

Channel I/O to I/O capacitance 0.15pF 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 4, 6 and 10 bump Chip Scale

Packages (CSP)

OptiGuard™ coated for improved reliability at

assembly

•

V_CCrail is protected from ESD strikes and eliminates

the need for a bypass capacitor to absorb positive

ESD strikes to ground. Each channel can safely

dissipate ESD strikes of 8kV, meeting the Level 4

requirement of the IEC61000-4-2 international

standard as well as 15kV air discharges per the

IEC61000-4-2 specification. Using the MIL-STD-

883 (Method 3015) specification for Human Body

Model (HBM) ESD, the pins are protected for

contact discharges at greater than 15kV.

•

RoHS-compliant, lead-free version finishing

Applications

This device is well-suited for next generation

wireless handsets that implement high-speed serial

interface solutions for the LCD display and camera

interfaces. In these designs, a tolerance above

1.5pF cannot be tolerated when high data rates are

transferred between the baseband choppiest and

the LCD driver/controller Is. Higher capacitive

loading normally causes the rise and fall times to

slow which hampers the functionality of circuit and

operation of the wireless handset. The CM1230

incorporates OptiGuard™ which results in improved

•

LCD and camera data lines in wireless

handsets that use high-speed serial interfaces.

I/O port protection for mobile handsets,

notebook computers, DSCs, MP3 players,

PDAs, etc. including USB, 1394 and serial ATA

reliability at assembly. The CM1230 is available in a

space-saving, low profile Chip Scale Package with

RoHS-compliant, lead-free finishing.
