USBUF01W6

Overview

The USBUF01W6 is a monolithic EMI filter and ESD protection device designed for USB upstream ports. It integrates recommended line termination with an Rt series resistor of 1500 Ω and Ct bypassing capacitors of 100 pF. The component features a low-pass EMI analogue filter specification to suppress radiated and conducted noise, ensuring compliance with FCC regulations. It provides robust electrostatic discharge protection exceeding IEC 61000-4-2 Level 4 standards, handling ±15 kV air discharge and ±8 kV contact discharge. Packaged in a compact SOT-323 (SOT323-6L) housing measuring 2.2mm x 1.35mm x 1mm, it supports industrial temperature ranges from -40°C to 150°C.

Feature Summary

• Integrates Rt series termination and Ct bypassing capacitors for USB upstream port line termination
• Provides EMI/RFI noise suppression through low-pass filtering characteristics
• Delivers high-level ESD protection compliant with IEC 61000-4-2 Level 4 requirements

Applications

• USB upstream port interface protection
• EMI/RFI noise suppression in USB systems
• ESD protection for data lines in high-density board designs

Procurement Notes

Verify the specific package variant, as sources indicate both standard SOT-323 and potential variations like SOT323-6L. Confirm RoHS compliance status via Ecopack2 documentation. Ensure the selected part matches the active USBUF01W6 designation rather than discontinued variants such as USBUF01W6-E. Cross-reference manufacturer datasheets for exact pinout and thermal specifications before integration.

Selection Notes

Select this component when designing USB upstream interfaces requiring integrated line termination and EMI filtering. It is suitable for applications needing compliance with FCC radiated emission limits without external discrete components. The small form factor aids in high-density PCB layouts. Ensure the design accounts for the integrated 1500 Ω resistance and 100 pF capacitance values to maintain signal integrity.
