ECLAMP2458P.TCT

The ECIamp2458P is a low pass (L-C) 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. This state-of-the-art device utilizes solid-state silicon-avalanche technology for superior clamping performance and DC electrical characteristics. They have been optimized for protection of color LCD and camera lines in cellular phones and other portable electronics.The device consists of eight identical circuits comprised of TVS diodes for ESD protection, and a 5-pole inductor capacitor network for EMI/RFI filtering. A typical inductor value of 28nH and a capacitor value of 12pF are used to achieve 40dB minimum attenuation at 800MHz. 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.The ECIamp2458P is in a 16-pin, RoHS/WEEE compliant, SLP4016P16 package. It measures 4.0 x 1.6 x 0.58mm. The leads are spaced at a pitch of 0.5mm and are finished with lead free NiPd. The small package makes it ideal for use in portable electronics such as cell phones, digital still cameras, and PDAs.
