CM1213A

1-, 2- and 4-Channel Low Capacitance ESD Protection Arrays

Features

Product Description

•

1, 2 and 4 channels of ESD protection

Provides ESD protection to IEC61000-4-2 Level 4

- 8kV contact discharge

The CM1213A 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

- 15kV air discharge

•

Low channel input capacitance of 0.85pF typical

Minimal capacitance change with temperature and

voltage

Channel input capacitance matching of 0.02pF

typical is ideal for differential signals

Mutual capacitance between signal pin and

adjacent signal pin - 0.11pF 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 lead-free packages

•

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

CM1213A will protect against ESD pulses up to 8kV

per the IEC 61000-4-2 standard and using the MIL•

STD-883D (Method 3015) specification for Human

Body Model (HBM) ESD, all pins are protected from

contact discharges of greater than 15kV.

•

Applications

•

USB2.0 ports at 480Mbps in desktop PCs,

notebooks and peripherals

These devices are particularly well-suited for protecting

systems using high-speed ports such as USB 2.0,

^{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.

•

^{IEEE1394 Firewire}® ports at 400Mbps / 800Mbps

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

•

The CM1213A family of devices is available with lead-

free finishing.

CM1213A

Application Information

Design Considerations

In order to realize the maximum protection against

ESD pulses, care must be taken in the PCB layout to

minimize parasitic series inductances on the Supply/

Ground rails as well as the signal trace segment

between the signal input (typically a connector) and the

ESD protection device. Refer to Figure 3, which

illustrates an example of a positive ESD pulse striking

an input channel. The parasitic series inductance back

inductance L on V by clamping V at the breakdown

2 CL P

voltage of the Zener diode. However, for the lowest

possible V , especially when V is biased at a voltage

significantly below the Zener breakdown voltage, it is

recommended that a 0.22μF ceramic chip capacitor be

connected between V and the ground plane.

As a general rule, the ESD Protection Array should be

located as close as possible to the point of entry of

expected electrostatic discharges. The power supply

bypass capacitor mentioned above should be as close

to the power supply is represented by L and L . The

voltage V on the line being protected is:

V_CL= Fwd voltage drop of D₁+ V_SUPPLY+ L₁x d(I_ESD) / dt

+ L₂x d(I_ESD) / dt

to the V pin of the Protection Array as possible, with

minimum PCB trace lengths to the power supply,

ground planes and between the signal input and the

ESD device to minimize stray series inductance.

where I

the positive supply voltage.

Additional Information

An ESD current pulse can rise from zero to its peak

value in a very short time. As an example, a level 4

contact discharge per the IEC61000-4-2 standard

results in a current pulse that rises from zero to 30

/Δt, or 30/(1x10 ). So just 10nH of series

ESD

inductance (L and L combined) will lead to a 300V

increment in V

Similarly for negative ESD pulses, parasitic series

inductance from the V pin to the ground rail will lead

to drastically increased negative voltage on the line

being protected.

The CM1213A has an integrated Zener diode between

V and V . This greatly reduces the effect of supply rail
