Semtech EClamp2122S
USB Downstream Port Filter & TVS For EMI Filtering and ESD Protection
The EClamp®2122S is combination EMI filter and line termination device with integrated TVS diodes for use
on USB interfaces. This device utilizes solid-state silicon-avalanche technology for superior clamping
performance and DC electrical characteristics. They have been optimized for protection of USB interfaces
in cellular phones and other portable electronics.
