CM1213
1, 2, 4, 6 and 8-Channel Low Capacitance ESD Protection Arrays
Features
Product Description
•
•
1, 2, 4, 6 and 8 channels of ESD protection
Provides ESD protection to IEC61000-4-2 Level 4
- 8kV contact discharge
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 neg-
- 15kV air discharge
•
•
Low loading capacitance of 1.0pF typical
Minimal capacitance change with temperature and
voltage
•
Channel I/O to GND capacitance difference of
0.02pF typical is ideal for differential signals
Channel I/O to I/O capacitance 0.8pF 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, SOIC and MSOP packages
Lead-free version available

between V and V , offering two advantages. First, it

protects the V 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 stan-
dard 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.

Applications
•
USB2.0 ports at 480Mbps in desktop PCs, note-
books and peripherals
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.
•
•
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
