CM1293A

2- and 4-Channel Low Capacitance ESD Protection Arrays

Features

•

2 and 4 channels of ESD protection

Note: For the 8-channel device, see the CM1293

datasheet.

Provides ESD protection to IEC61000-4-2

• ±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 lead-free SOT and MSOP packages

Product Description

The CM1293A 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 negative ESD current pulse to

either the positive (V

P

) or negative (V

N

) supply rail. A

Zener diode is embedded between V

P

and V

N

, offering

two advantages. First, it protects the V

CC

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

CM1293A will protect against ESD pulses up to

±8kV

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

standard.

This device is particularly well-suited for protecting

systems 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 CM1293A family of devices is available with lead-

free finishing.

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.
