Semtech EClamp2485T
ESD/EMI Protection for SIM Card
The EClamp® 2485T is combination EMI filter and line termination device with integrated TVS diodes for use
on SIM Card interfaces that utilize the Single Wire Protocal (SWP) line. This device utilizes solid-state
silicon-avalanche technology for superior clamping performance and DC electrical characteristics. They
have been optimized for protection of SIM interfaces in cellular phones with NFC capability.
