PROTECTION PRODUCTS - EMIClampTM Description The EClampTM2384K is a low pass filter array with integrated TVS diodes. It is designed to suppress unwanted EMI/RFI signals and provide 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. It has been optimized for protection of color LCD panels in cellular phones and other portable electronics. The device consists of four identical circuits comprised of TVS diodes for ESD protection, and a resistor capacitor network for EMI/RFI filtering. A series resistor value of 200Ω and a capacitance value of 12pF are used to achieve 30dB minimum attenuation from 800MHz to 2.7GHz. The TVS diodes provide effective suppression of ESD voltages in excess of ±15kV (air discharge) and ±8kV (contact discharge) per IEC 610004-2, level 4. The EClamp2384K is in a 8-pin, RoHS/WEEE compliant, SLP1713P8 package. It measures 1.7 x 1.3 x 0.50mm. The leads are spaced at a pitch of 0.4mm and are finished with lead-free NiPdAu. The small package makes it ideal for use in portable electronics such as cell phones, digital still cameras, and PDAs.

The device is in a 8-pin SLP package. Electrical connection is made to the 8 pins located at the bottom of the device. A center tab serves as the ground connection. The device has a flow through design for easy layout. Pin connections are noted in Figure 1. All path lengths should be kept as short as possible to minimize the effects of parasitic inductance in the board traces. Recommendations for the ground connection are given below.
