More Info

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 (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 CM1213 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 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.

Note: Some of the devices listed here have suggested replacements available. Please see additional information at the end of this page.

FEATURES

APPLICATIONS

6 or 8 channels of ESD protection
Note: For1, 2, and 4 channel devices, see the CM1213A datasheet.
Provides ESD protection to IEC61000-4-2
Level 4
- ±8kV contact discharge
Low channel input capacitance of 1.0pF 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 SOIC and MSOP, lead-free packaging

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