Product Description
The CM1218 family of devices features transient volt-
age suppressor arrays that provide a very high level of
protection for sensitive electronic components which
may be subjected to electrostatic discharge (ESD).
All pins of the CM1218 are rated to withstand
±15kV
ESD pulses using the IEC 61000-4-2 contact dis-
charge method. Using the MIL-STD-883D (Method
3015) specification for Human Body Model (HBM)
ESD, all pins are protected from contact discharges of
greater than
±30kV.
The CM1218 is supplied in a number of compact, sur-
face mount packages depending on the channel con-
figuration desired. All versions of this device are
available with optional lead-free finishing.
Applications
•
•
•
High-speed consumer electronic ports
ESD protection of PC ports, including USB ports,
serial ports, parallel ports, IEEE1394 ports,
docking ports, proprietary ports, etc.
Protection of interface ports or IC pins which are
exposed to high ESD levels
