SEMTECH STF203-15 THRU STF203-33 handbook
The STF203 is a combination EMI filter and line termination device featuring integrated TVS diodes designed for use on upstream USB ports. It utilizes proprietary technology to integrate passive components and TVS diodes into a single SC70-6L package, providing termination, filtering, and ESD protection for one port in compliance with USB specification revision 1.1.
The device offers bidirectional EMI/RFI filtering and line termination with integrated ESD protection rated up to IEC 61000-4-2 Level 4 (15kV air discharge, 8kV contact discharge). It is available in three variants based on series resistance values: STF203-15 (15Ω), STF203-22 (22Ω), and STF203-33 (33Ω).
