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 channel input capacitance of 1.0pF typical
Minimal capacitance change with temperature and
voltage
•
•
•
Channel input capacitance matching of 0.02pF typ-
ical is ideal for differential signals
Mutual capacitance between signal pin and adja-
cent 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, SOIC and MSOP packages
Lead-free version available
ative ESD current pulse to either the positive (V ) or
P
negative (V ) supply rail. A Zener diode is embedded
N
between V and V , offering two advantages. First, it
P
N
protects the V rail against ESD strikes, and second,
CC
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
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
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.
