The EClamp
integrated TVS diodes. It is designed to suppress
unwanted EMI/RFI signals and provide electrostatic
discharge (ESD) protection in portable electronic
equipment. They have been optimized for protection

The device consists of six pi filter circuits comprised of
TVS diodes for ESD protection, and a resistor capacitor
network for EMI/RFI filtering. A series resistor value of
100
are used to achieve 20dB minimum attenuation from
1.0GHz to 3GHz. The device also includes 4 discrete
TVS diodes for dedicated ESD protection. All of the
TVS diodes provide effective suppression of ESD
voltages in excess of ±15kV (air discharge) and ±8kV
(contact discharge) per IEC 61000-4-2, level 4.
