NUF3101FCT1

Overview

The NUF3101FCT1 is an ESD protection and EMI/RFI filter component manufactured by onsemi. It features a PI-filter topology designed for surface-mount applications. The device operates within a temperature range of -40°C to +85°C. It is classified as an ESD suppressor or TVS diode variant integrated with filtering capabilities. The component utilizes FlipChip-15 packaging, ensuring compact integration into high-density circuit boards while providing signal integrity protection against electrostatic discharge events.

Feature Summary

• Integrates ESD suppression with EMI/RFI filtering in a single compact package
• Utilizes PI-filter topology to maintain signal integrity during operation
• Designed for surface-mount installation using FlipChip-15 packaging

Applications

• ESD protection for high-speed data lines
• EMI/RFI filtering in portable electronic devices
• Signal conditioning for consumer electronics interfaces

Procurement Notes

Verify the current lifecycle status before procurement, as the component may be marked as obsolete or discontinued. Confirm availability through authorized distributors only. Ensure the specific FlipChip-15 package variant matches the design requirements. Check for RoHS compliance documentation if required by regional regulations. Validate that the intended application does not require active components if passive filtering suffices.

Selection Notes

Select this component when simultaneous ESD protection and high-frequency noise attenuation are required in space-constrained designs. The PI-filter structure offers superior performance compared to discrete solutions. Consider the FlipChip-15 footprint for board layout compatibility. Evaluate thermal operating limits relative to the final assembly environment. Compare against standard TVS diodes if filtering is not a primary requirement.

Part Context

This part belongs to onsemi's portfolio of ESD protection and filtering solutions. It is categorized under ESD suppressors and TVS diodes with added filtering functionality. The product line targets markets requiring robust signal integrity management. It complements other passive and active filtering components offered by the manufacturer for comprehensive circuit protection strategies.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify cross-reference options through official onsemi channels. Ensure any alternative component matches the FlipChip-15 package dimensions and electrical characteristics. Check for equivalent PI-filter topology if signal integrity is critical.
