EClamp2378P ESD/EMI Protection for Color LCD Interfaces TM PROTECTION PRODUCTS - EMIClampPROTECTION PRODUCTS PRELIMINARY Features Description TM The EClamp 2378P 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) Level 4, 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- 1.8GHz 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 Typical Capacitance: 20pF (VR = 0V) electronics. Protection and filtering for eight lines The device consists of eight identical circuits comprised Solid-state technology of TVS diodes for ESD protection, and a resistor - Mechanical Characteristics capacitor network for EMI/RFI filtering. A series resistor value of 100 and a capacitance value of SLP4016P16 16-pin package 10pF are used to achieve 30dB minimum attenuation RoHS/WEEE Compliant from 1.8GHz to 2.5GHz. The TVS diodes provide Nominal Dimensions: 4.0 x 1.6 x 0.58 mm effective suppression of ESD voltages in excess of Lead Pitch: 0.5mm 15kV (air discharge) and 8kV (contact discharge) per Lead finish: NiPd IEC 61000-4-2, level 4. Marking : Marking Code Packaging : Tape and Reel per EIA 481 The EClamp2378P is in a 16-pin, RoHS/WEEE compli- ant, SLP4016P16 package. It measures 4.0 x 1.6 x Applications 0.58mm. The leads are spaced at a pitch of 0.5mm Color LCD Protection and are finished with lead-free NiPd. The small pack- Cell Phone CCD Camera Lines age makes it ideal for use in portable electronics such Clamshell Cell Phones as cell phones, digital still cameras, and PDAs.
