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 Block Diagram ©2010 SCILLC.
