EClamp2342N ESD/EMI Protection for Color LCD Interfaces TM PROTECTION PRODUCTS - EMIClampPROTECTION PRODUCTS PRELIMINARY Features Description TM The EClamp 2342N is a low pass filter array with Bidirectional EMI/RFI filter with integrated TVS integrated TVS diodes. It is designed to suppress for ESD protection unwanted EMI/RFI signals and provide electrostatic ESD protection to IEC 61000-4-2 (ESD) Level4, discharge (ESD) protection in portable electronic 15kV (air), 8kV (contact) equipment. This state-of-the-art device utilizes solid- Filter performance: 30dB minimum attenuation state silicon-avalanche technology for superior clamp- 1GHz to 2.5GHz ing performance and DC electrical characteristics. TVS working voltage: 5V protection of colorprotection of colorprotection of color They have been optimized for protection of colorprotection of color Resistor: 100 +/ 15% LCD panelsLCD panelsLCD LCD panelsLCD panelspanels in cellular phones and other portable Input Capacitance: 20pF (VR = 0V) electronics. Protection and filtering for eight lines Solid-state technology The device consists of eight identical circuits comprised of TVS diodes for ESD protection, and a resistor - Mechanical Characteristics capacitor network for EMI/RFI filtering. A series 16 pin QFN resistor value of 100 and a capacitance value of RoHS/WEEE Compliant 20pF are used to achieve 30dB minimum attenuation Nominal Dimensions: 3.0 x 3.0 x 1.0 mm from 1GHz to 2.5GHz. Each line features two stages of Lead Pitch: 0.5mm TVS diode protection. The TVS diodes provide effec- tive suppression of ESD voltages in excess of 15kV Lead finish: Matte Tin (air discharge) and 8kV (contact discharge) per Marking : Marking Code + Date Code IEC 61000-4-2, level 4. Packaging : Tape and Reel per EIA 481 Applications The EClamp2342N is in a 16-pin, 0.5mm pitch QFN package. It measures 3.0 x 3.0 x 1.0mm. The small Color LCD Panel Protection package makes it ideal for use in portable electronics Cell Phone CCD Camera Lines such as cell phones, digital still cameras, and PDAs.
