CM1213

6 and 8-Channel Low Capacitance ESD Protection Arrays

Product Description

The CM1213 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 embedded between V protects the V need for a bypass capacitor that would otherwise be needed for absorbing positive ESD strikes to ground. The CM1213 will protect against ESD pulses up to ±8 kV per the IEC 61000−4−2 standard.

These devices are particularly well−suited for protecting systems using high−speed ports such as USB2.0, IEEE1394 (Firewire iLinkt), 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.

*Standard test condition is IEC61000−4−2 level 4 test circuit with each pin subjected to ±8 kV 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.
