16 Pin SLP package (Bottom Side View)
The EClampTM2388K is a low pass filter array with integrated TVS diodes. It is designed to suppress un- wanted EMI/RFI signals and provide electrostatic dis- charge (ESD) protection in portable electronic equip- ment. 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 panelsprotection of color LCD panelsprotection of color LCD panelsprotection of color LCD panelsprotection of color LCD panels in cellular phones and other portable electronics. The device consists of eight 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 61000- 4-2, level 4. The EClamp2388K is in a 16-pin, RoHS/WEEE compli- ant, SLP3313P16 package. It measures 3.3 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. Mechanical Characteristics Circuit Diagram (Each Line)

5© 2007 Semtech Corp. www.semtech.com PRELIMINARYPROTECTION PRODUCTS EClamp2388K Applications Information Figure 3 shows the recommended device layout. The ground pad vias have a diameter of 0.008 inches (0.20 mm) while the two external vias have a diameter of 0.010 inches (0.250mm). The internal vias are spaced approximately evenly from the center of the pad. The designer may choose to use more vias with a smaller diameter (such as 0.005 inches or 0.125mm) since changing the diameter of the via will result in little change in inductance (i.e. the log function in Equation 2 in highly insensitive to parameter d) . Figure 4 shows a typical insertion loss (S21) plot for the device using Semtech’s filter evaluation board with 50 Ohm traces and the recommended via configuration.
