ECLAMP2357NQTCT

The EClamp®
2357NQ is a low pass filter array with
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 of
touch screen displays, secure digital (SD) card interfaces,
and color LCD panels in cellular phones and other
portable electronics.
The device consists of six π filter circuits comprised of
TVS diodes for ESD protection, and a resistor capacitor
network for EMI/RFI filtering. A series resistor value of
100Ω and a component capacitance value of 10pF 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 ±20kV (air discharge) and ±12kV (contact discharge)
per IEC 61000-4-2, level 4.
The EClamp2357NQ is qualified to AEC-Q100 Grade 1 for
automotive use.
