- EMIClamp TM Description
The EClamp 3202A is a low pass filter array with integrated TVS diodes for ESD protection. It is designed to provide bidirectional filtering of EMI/RFI signals and electrostatic discharge (ESD) protection in portable electronic equipment. This state-of-the-art device utilizes solid-state silicon-avalanche technology for superior clamping performance and DC electrical characteristics. They have been optimized for use on a microphone port in cellular phones and other protable electronics. The EClamp3202A effectively replaces 10 discrete ponents in a small SC-89 package to provide ESD protection and EMI filtering. Each device requires less than 2.9mm2 of PCB area with a low profile of only 0.60mm. This small package will protect and filter up to two lines. This small outline makes the device especially well suited for portable applications. The TVS diodes are bidirectional for supporting bipolar audio signals without distortion. The TVS diodes provide effective suppression of ESD voltages in excess of 15k V (air discharge) and 8k V (contact discharge) per IEC 61000-4-2, level 4. The device has very low insertion loss in the pass band and high attenuation at frequencies ranging from 800MHz to 3GHz. Each line Features two stages of TVS diode protection. They feature large cross-sectional area junctions for conducting high transient currents. They offer desirable characteristics for...
