1 / 8 page PROTECTION PRODUCTS 1 www.semtech.com PRELIMINARY PROTECTION PRODUCTS - EMIClampTM EClamp2378K ESD/EMI Protection for Color LCD Interfaces Description Features Package Configuration 16 Pin SLP package (Bottom Side View) Nominal Dimensions in mm The EClampTM2378K 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. This state-of-the-art device utilizes solid- state silicon-avalanche technology for superior clamp- ing performance and DC electrical characteristics. They have been optimized for protection of color protection of color protection of color protection of color protection of color LCD panels LCD panels LCD panels LCD panels LCD panels in cellular phones and other portable electronics. The device consists of eight identical circuits comprised of TVS diodes for ESD protection, and a resistor - capacitor network for EMI/RFI filtering. A series resistor value of 100 Ω and a capacitance value of 10pF are used to achieve 30dB minimum attenuation from 1.8GHz to 2.5GHz. 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 EClamp2378K is in a 16-pin, RoHS/WEEE compli- ant, SLP3313P16 package. It measures 3.3 x 1.3 x 0.50mm. The leads are spaced at a pitch of 0.4mm and are finished with lead-free NiPdAu. The small package makes it ideal for use in portable electronics such as cell phones, digital still cameras, and PDAs.
