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 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.
