NUF6402MNT1G

Overview

The NUF6402MNT1G is a unidirectional ESD protection device and TVS diode from onsemi, featuring an integrated 4-channel EMI Pi filter. It operates at a working voltage of 5 V with a breakdown voltage of 6 V. The component utilizes a DFN-12 surface-mount package and exhibits a diode capacitance of 20 pF. It provides electrostatic discharge protection rated at 8 kV contact discharge. The device functions within a temperature range of -40 C to +85 C.

Feature Summary

• Integrates four channels of EMI filtering with ESD suppression capabilities
• Provides bidirectional signal line protection against transient voltage events
• Utilizes low-profile surface-mount packaging for compact circuit board layouts

Applications

• Protection of high-speed data lines in portable electronic devices
• ESD mitigation for USB interface circuits
• Signal line filtering in mobile communication modules

Procurement Notes

Verify the specific ordering suffix and tape-and-reel specifications before procurement. Confirm that the DFN-12 package dimensions align with the target PCB footprint. Ensure compliance with RoHS directives if required by the end application. Check for any recent product change notifications regarding assembly sites or material composition updates.

Selection Notes

Select this component when designing circuits requiring simultaneous ESD protection and EMI attenuation for multiple signal lines. The 5 V operating voltage makes it suitable for low-voltage digital interfaces. Consider the 20 pF capacitance value to ensure signal integrity is maintained at the intended data rates. Verify that the 8 kV contact discharge rating meets the system's environmental stress requirements.

Part Context

This part belongs to the NUF6402 series of EMI filters with integrated ESD protection. It is categorized under ESD suppressors and TVS diodes within onsemi's portfolio. The device is designed to replace discrete components by combining filtering and protection functions into a single compact package, reducing overall solution size and complexity.

Replacement Considerations
