Product Description
The CM1213A family of diode arrays has been designed to provide ESD protection for electronic components or subsystems 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 (VP) or negative (VN) supply rail. A Zener diode is embedded between VP and VN, offering two advantages. First, it protects the VCC 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. These devices are particularly well-suited for protecting systems using high-speed ports such as USB 2.0, IEEE1394 (Firewire(R), iLinkTM), 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 CM1213A family of devices is available with RoHS-compliant, lead-free finishing.

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 Error! Reference source not found., which illustrates an example of a positive ESD pulse striking an input channel. The parasitic series inductance back to the power supply is represented by L1 and L2. The voltage VCL on the line being protected is:
VCL = Fwd + L2 x d(IESD) / dt voltage drop of D1 + VSUPPLY + L1 x d(IESD)
/
dt
where IESD is the ESD current pulse, and VSUPPLY is the positive supply voltage. 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 Amps in 1ns. Here -9 d(IESD)/dt can be approximated by IESD/t, or 30/(1x10 ). So just 10nH of series inductance (L1 and L2 combined) will lead to a 300V increment in VCL! Similarly for negative ESD pulses, parasitic series inductance from the VN 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 VP and VN. This greatly reduces the effect of supply rail inductance L2 on VCL by clamping VP at the breakdown voltage of the Zener diode. However, for the lowest possible VCL, especially when VP is biased at a voltage significantly below the Zener breakdown voltage, it is recommended that a 0.22F ceramic chip capacitor be connected between VP 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 VP 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.
