Low Capacitance Transient Voltage
Suppressors / ESD Protectors
CM1218-C4
Features
• Low I/O capacitance at 7pF typical
• Four channels of ESD protection
• In-system ESD protection to ±15kV contact
discharge, per the IEC 61000-4-2 international
standard
• Compact SMT package saves board space and
facilitates layout in space-critical applications
• Each I/O pin can withstand over 1000 ESD
strikes
• RoHS-compliant, lead-free
Note: For other versions of the CM1218, see the
CM1218 datasheet or the CM1218-H4
datasheet.
Product Description
The CM1218-C4 device features transient voltage
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-C4 are rated to withstand
±15kV ESD pulses using the IEC 61000-4-2 contact
discharge 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 CM1218C4 is supplied in an SOT-553, RoHS-
compliant, lead-free finished package.
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
