SEMTECH ECLAMP2455P.TCT

The EClampTM2455P 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. 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 61000 - 4 - 2, level 4. An additional TVS diode connection is included for protection of the voltage (Vcc) bus. The EClamp2455P is in a 8-pin, RoHS/WEEE compliant, SLP2116P8 package. It measures 2.1×1.6× 0.58mm. The leads are spaced at a pitch of 0.5mm 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.
