Low Capacitance Transient Voltage Suppressors / ESD Protectors CM1219
Features
* * * * * * Low I/O capacitance at 4pF typical In-system ESD protection to 8kV contact discharge, per the IEC 61000-4-2 international standard Five channels of ESD protection Compact SMT package saves board space and facilitates layout in space-critical applications Each I/O pin can withstand over 1000 ESD strikes* Lead-free version packaging
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
Product Description
The CM1219 family of devices 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 CM1219 are rated to withstand 8kV 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 15kV.

*Standard test condition is
IEC61000-4-2 level 4 test circuit with each pin subjected to 8kV contact discharge for 1000 pulses. Discharges are timed at 1 second intervals and all 1000 strikes are completed in one continuous test run. The part is then subjected to standard production test to verify that all of the tested parameters are within spec after the 1000 strikes.
