CM1215

CM1215 1, 2 and 4-Channel Low Capacitance ESD Arrays Product Description The CM1215 family of diode arrays provides 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 CM1215 protects against ESD pulses up to ±15 kV 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®, 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. Features One, two, and four 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 0.04 pF Typical Mutual Capacitance of 0.13 pF Typical Minimal Capacitance Change with Temperature and Voltage Each I/O Pin Can Withstand Over 1000 ESD Strikes SOT Packages These Devices are Pb−Free and are RoHS Compliant Applications IEEE1394 Firewire® Ports at 400 Mbps / 800 Mbps DVI Ports, H...
