NUF2042XV6T1G

Overview

The NUF2042XV6T1G is a bidirectional ESD protection diode array manufactured by onsemi, designed for USB upstream termination. It features a complex array configuration with five internal elements housed in an ESV (SOT-563) surface-mount package measuring 1.7mm x 1.3mm x 0.6mm. The device has a maximum reverse standoff voltage of 3.3V and a breakdown voltage of 5.6V at a test current of 1mA. It supports a peak pulse power dissipation of 0.22W and operates within a temperature range of -55°C to 125°C. The component includes six pins and exhibits a maximum reverse leakage current of 100nA.

Feature Summary

• Integrated USB upstream terminator functionality combined with electrostatic discharge protection
• Bidirectional protection architecture suitable for differential signal lines
• Compact surface-mount packaging optimized for space-constrained designs

Applications

• USB upstream port termination circuits
• Electrostatic discharge protection for high-speed data interfaces
• Signal line protection in portable electronic devices

Procurement Notes

Verify the specific ordering suffix and tape-and-reel quantity against official distributor catalogs before purchase. Confirm that the ESV package variant matches your PCB footprint requirements. Ensure compliance with RoHS directives if required by your manufacturing standards. Cross-reference the manufacturer part number with authorized supply channels to avoid counterfeit components.

Selection Notes

Select this component when a combined ESD suppressor and USB terminator is required for upstream ports. The low capacitance and bidirectional nature make it suitable for protecting differential pairs. Consider the SOT-563 package dimensions during layout planning. Verify that the 3.3V standoff voltage aligns with the operating voltage of the protected circuit lines.

Part Context

This device belongs to onsemi's family of ESD protection diodes and TVS diodes. It is categorized under EMI/RFI filters and RC networks due to its integrated filtering characteristics. The product serves as a specialized solution for interface protection, distinct from general-purpose transient voltage suppressors.

Replacement Considerations

Check for direct substitutes within the NUF series or equivalent bidirectional arrays from other manufacturers. Ensure replacement parts match the 3.3V Vwm and 5.6V Vbr specifications. Verify package compatibility with the SOT-563 form factor.
