Description

The EClamp2374KQ 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 for Automotive grade electronics. The device consists of four identical channels comprised of TVS diodes for ESD protection, and a resistor-capacitor network optimized for EMI/RFI filtering. A series resitor value of 100Ω and a capacitance value of 10pF are used to achieve 30dB minimum attenuation from 1.8GHz to 2.5GHz. The TVS diodes provide effective suppression of ESD voltages in excess of ±15kV (air discharge) and ±8kV (contact discharge) per IEC61000-4-2, level 4. The EClamp2374KQ is packaged in an 8-pin, SLP1713P8 package. The package dimensions measure 1.7 x 1.3 x 0.5mm. The leads are spaced at a pitch of 0.4mm and are finished with a lead-free NiPdAu.

Application 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. Figure 5 shows a typical insertion loss (S21) plot using a similar board without the internal ground pad vias. The result is a more inductive ground loop. Note the “hump” at a frequency of 2.5GHz. This is the resonant frequency of the higher ground loop inductance.
