CM1210
1, 2, 4 and 8-Channel Very Low Capacitance ESD Protectors
Features
•
•
•
•
•
1,2,4 and 8 channels of ESD protection
Very low loading capacitance (1.0pF typical)
+
6 kV ESD protection per channel (IEC 61000-4-2
standard)
Available in SOT23, SOT143, SC70 and MSOP
packages
Lead-free versions available
Product Description
The CM1210 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 which will steer the ESD current pulse to
either the positive (V
P
) or negative (V
N
) supply rail. The
CM1210 will protect against ESD pulses up to
+
6KV
per the IEC 61000-4-2 standard.
This device is particularly well-suited for systems using
high-speed port implementations such as USB2.0,
IEEE1394 (Firewire
, i.Link
), Gigabit Ethernet and
corresponding ports in removable storage, digital cam-
corders, DVD-RW drives and other applications where
extremely low loading capacitance with ESD protection
are required in a small package footprint.
The CM1210 family of devices is optionally available
with lead-free finishing.
