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.
