EClamp2455K ESD/EMI Protection for SIM Card PRELIMINARY PROTECTION PRODUCTS - EMIClampTM Description Features The EClampTM2455K is combination EMI filter and line termination device with integrated TVS diodes for use on SIM Card interfaces on cellular phones and other portable electronics. This state-of-the-art device utilizes solid-state silicon-avalanche technology for superior clamping performance and DC electrical characteristics. Bidirectional EMI/RFI filter with integrated TVS for ESD protection ESD protection to IEC 61000-4-2 (ESD) Level 4, The device consists of three circuits that include series impedance matching resistors for proper termination of the SIM card interface. Termination resistor value of 100 Ohms is included on the RST and Data lines and 47 Ohms on the CLK line. TVS diodes are also included on each line for ESD protection in excess of ±15kV (air discharge) and ±8kV (contact discharge) per IEC 610004-2, level 4. An additional TVS diode connection is included for protection of the voltage (Vcc) bus. ±15kV (air), ±8kV (contact) TVS working voltage: 5V Termination Resistors: 100 Ohms & 47 Ohms Capacitance: 20pF (Typical at VR = 0V) Protection and filtering for four lines Solid-state technology Mechanical Characteristics The EClamp2455K 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 and digital still cameras.

The package has flow through design which allows the designer to route the signals straight in and out between the SIM port connector and the SIM controller. 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. 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.
