ECLAMP3202A

EClamp3202A ESD/EMI Protection for Microphone Ports TM PROTECTION PRODUCTS - EMIClampPROTECTION PRODUCTS PRELIMINARY Features Description TM The EClamp 3202A is a low pass filter array with Transient protection for data lines to integrated TVS diodes for ESD protection. It is de- IEC 61000-4-2 (ESD) 15kV (air), 8kV (contact) signed to provide bidirectional filtering of EMI/RFI IEC 61000-4-4 (EFT) 40A (5/50ns) signals and electrostatic discharge (ESD) protection in Bidirectional EMI/RFI filter with integrated ESD portable electronic equipment. This state-of-the-art protection device utilizes solid-state silicon-avalanche technology Protects two I/O lines for superior clamping performance and DC electrical Ultra-small SC-89 package (1.7 x 1.7 x 0.6mm1.7 x 1.7 x 0.6mm1.7 x 1.7 x 0.6mm) 1.7 x 1.7 x 0.6mm1.7 x 1.7 x 0.6mm characteristics. They have been optimized for use on a 2 requires less than 2.9mm of PCB area microphone port in cellular phones and other protable Working voltage: 5V electronics. The EClamp3202A effectively replaces 10 Low leakage current discrete components in a small SC-89 package to Low operating and clamping voltages provide ESD protection and EMI filtering. Each device 2 Solid-state silicon-avalanche technology requires less than 2.9mm of PCB area with a low profile of only 0.60mm. This small package will protect Mechanical Characteristics and filter up to two lines. This small outline makes the SC-89 (SOT-666) package device especially well suited for portable applications.
