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, RoHScompliant, 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
