USB Upstream Port Filter & TVS for EMI Filtering and ESD Protection

The STF203-15/22/33 is a combination EMI filter and line termination device with integrated TVS diodes for use on upstream USB ports. It is constructed using a proprietary technology that allows passive components and TVS diodes to be integrated in the same package. Each device will provide termination, filtering, and ESD protection for one upstream USB port.
