EClamp2422N ESD/EMI Protection for Audio Interfaces TM PPROTECTION PRODUCTS - EMIClampROTECTION PRODUCTS PRELIMINARY Features Description TM The EClamp 2422N is a (C-L-C) 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- TVS working voltage: 5V state silicon-avalanche technology for superior clamp- Inductor: 2nH (Typical) ing performance and DC electrical characteristics. It protection of headsetprotection of headset Capacitors: 100pF (Typical at VR = 0V) has been optimized for protection of headsetprotection of headsetprotection of headset audio portsaudio portsaudio audio portsaudio portsports in cellular phones and other portable Protection and filtering for two lines electronics. Solid-state technology The device consists of two identical circuits comprised of Mechanical Characteristics TVS diodes for ESD protection, and a C-L-C pi-filter for SLP1510N6 6-pin package EMI/RFI filtering. A typical inductor value of 2nH and a RoHS/WEEE Compliant capacitor value of 100pF are used to achieve 20dB Nominal Dimensions: 1.45 x 1.0 x 0.58 mm minimum attenuation from 800MHz to 2.7GHz. It has a Lead Pitch: 0.5mm very low series resistance of 2 Ohms, making it ideal for Lead finish: NiPdAu use on headset speaker interfaces. The TVS diodes provide effective suppression of ESD voltages in excess of Marking: Marking Code 15kV (air discharge) and 8kV (contact discharge) per Packaging: Tape and Reel per EIA 481 IEC 61000-4-2, level 4. Applications The EClamp2422N is in a 6-pin, RoHS/WEEE compliant, Cellular Handsets SLP1510N6 package. It measures 1.45 x 1.0 x Speaker Ports in Portables 0.58mm. The leads are spaced at a pitch of 0.5mm Notebook Computers and are finished with lead-free NiPdAu. The small package makes it ideal for use in portable electronics.
