EClamp2384K ESD/EMI Protection for Color LCD Interfaces TM PROTECTION PRODUCTS - EMIClampPROTECTION PRODUCTS PRELIMINARY Features Description TM The EClamp 2384K is a low pass filter array with Bidirectional EMI/RFI filter with integrated TVS integrated TVS diodes. It is designed to suppress un- for ESD protection wanted EMI/RFI signals and provide electrostatic dis- ESD protection to IEC 61000-4-2 (ESD) Level 4, charge (ESD) protection in portable electronic equip- 15kV (air), 8kV (contact) ment. This state-of-the-art device utilizes solid-state Filter performance: 30dB minimum attenuation silicon-avalanche technology for superior clamping 800MHz to 2.7GHz performance and DC electrical characteristics. It has TVS working voltage: 5V protection of color LCD panelsprotection of color LCD panelsprotection of color LCD panels been optimized for protection of color LCD panelsprotection of color LCD panels Resistor: 200 +/ 15% in cellular phones and other portable electronics. Typical Capacitance: 12pF (VR = 2.5V) Protection and filtering for four lines The device consists of four identical circuits comprised of TVS diodes for ESD protection, and a resistor - Solid-state technology capacitor network for EMI/RFI filtering. A series Mechanical Characteristics resistor value of 200 and a capacitance value of 12pF are used to achieve 30dB minimum attenuation from SLP1713P8 8-pin package 800MHz to 2.7GHz. The TVS diodes provide effective RoHS/WEEE Compliant suppression of ESD voltages in excess of 15kV (air Nominal Dimensions: 1.7 x 1.3 x 0.50 mm discharge) and 8kV (contact discharge) per IEC 61000- Lead Pitch: 0.40mm 4-2, level 4. Lead finish: NiPdAu Marking: Marking Code The EClamp2384K is in a 8-pin, RoHS/WEEE compliant, Packaging: Tape and Reel per EIA 481 SLP1713P8 package. It measures 1.7 x 1.3 x 0.50mm. The leads are spaced at a pitch of 0.4mm and are Applications finished with lead-free NiPdAu. The small package Color LCD Protection makes it ideal for use in portable electronics such as Cell Phone CCD Camera Lines cell phones, digital still cameras, and PDAs.
