PRELIMINARY CM1216 6- and 8-Channel Low Capacitance ESD Arrays Features • • • • • • • • • 6 and 8 channels of ESD protection Provides +15 kV ESD protection on each channel per the IEC 61000-4-2 ESD requirements Channel loading capacitance of 1.6 pF typical Channel I/O to GND capacitance difference of 0.04pF typical Mutual capacitance of 0.13pF typical Minimal capacitance change with temperature and voltage Each I/O pin can withstand over 1000 ESD strikes SOIC and MSOP packages Lead-free versions available Product Description The CM1216 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 (VP) or negative (VN) supply rail. The CM1216 will protect against ESD pulses up to +15kV per the IEC 61000-4-2 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 CM1216 family of devices is available with optional lead-free finishing.

Refer to Figure 1, 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 voltage drop of D1 + VSUPPLY + L1 x d(IESD) / dt+ L2 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 d(IESD)/dt can be approximated by d(ESD)/dt, or 30/(1x10-9). 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. 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.
