Overview
The onsemi NUF4402MNT1G is a specialized integrated circuit designed as a four-channel EMI/RFI filter with built-in electrostatic discharge (ESD) protection. It utilizes a C-R-C network topology to suppress electromagnetic interference on data lines while safeguarding connected components from voltage transients. The device operates within an ambient temperature range of -40°C to +85°C and is housed in a compact 8-lead VFDFN package with an exposed pad, measuring 1.60mm x 1.60mm. This component is specifically engineered for high-speed data line applications in mobile devices.
Feature Summary
- Integrates four-channel low-capacitance ESD protection diodes with passive filtering elements
- Employs C-R-C network architecture to attenuate high-frequency noise and EMI
- Features bidirectional TVS array structure for comprehensive transient suppression
- Designed for space-constrained mobile device applications requiring signal integrity
Applications
- Data line protection in mobile handsets
- EMI suppression for high-speed digital interfaces
- ESD protection for USB or similar data ports
Procurement Notes
Verify the specific datasheet revision and ordering suffix when sourcing. Confirm that the DFN-8 package dimensions match the target PCB footprint. Ensure the bidirectional configuration aligns with the circuit's polarity requirements. Check for any recent product change notices regarding assembly sites or material compliance updates before finalizing procurement.
Selection Notes
Select this component when simultaneous ESD protection and EMI filtering are required on multiple data lines. The low capacitance characteristic preserves signal integrity for high-speed interfaces. Consider the thermal performance of the exposed pad for heat dissipation if operating near maximum temperature limits. Evaluate the trade-off between filtering effectiveness and insertion loss for the specific data rate.
Part Context
This part belongs to onsemi's family of integrated EMI filters with ESD protection. It combines semiconductor protection structures with passive LC/RC networks into a single small-footprint package. This integration reduces board space compared to discrete solutions and simplifies assembly processes for consumer electronics manufacturers seeking robust signal conditioning.
Replacement Considerations
NUF6402MNT1G: Offers four channels but in a larger DFN-12 package with different pinout. NUF8402MNT4G: Provides eight channels in a DFN-16 package. Verify pin compatibility and electrical specifications before substituting.
