This information is based on SEMTECH's official datasheet for the STF203-22.TCT.

Application Scenarios & Design Considerations

USB Upstream Port Filter and TVS

Alternative Part Number

  • USBLC6-2SC6 --: Dual-line ESD protection diode array in SOT-23-6, functionally similar to the STF203-22 for USB/ESD clamping applications.
  • SRV05-4.TCT --: Same manufacturer's 4-line ESD protection array with comparable clamping performance, suitable as a higher-channel-count substitute.
  • TPD2E001DRLR --: Two-channel ESD protection device in small package with similar working voltage and low capacitance, good drop-in functional alternative.
