CM1213A
1-, 2- and 4-Channel Low Capacitance ESD Protection Arrays
Features
• 1, 2 and 4 channels of ESD protection
• Provides ESD protection to IEC61000-4-2 Level 4
- 8kV contact discharge
- 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
Applications
• USB2.0 ports at 480Mbps in desktop PCs,
notebooks and peripherals
• 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
Product Description
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
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 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.
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.
The CM1213A family of devices is available with lead-
free finishing.
