SZNUF6401MNWT1G

Overview

The SZNUF6401MNWT1G is a six-channel EMI filter array with integrated ESD protection, utilizing a C-R-C Pi-style topology. It features typical component values of R = 100 Ω and C = 17 pF, providing a cutoff frequency of 110 MHz. The device achieves greater than -30 dB stopband attenuation in the 800 MHz to 3.0 GHz range. It supports data rates up to 74 Mbps for parallel interfaces and offers ±15 kV ESD protection per channel under IEC61000-4-2 contact discharge standards. Packaged in a low-profile 12-pin DFNW12 surface-mount format with wettable flanks.

Feature Summary

• Integrated ESD protection capability of ±15 kV per channel ensures robust defense against electrostatic discharge events.
• Six-channel C-R-C Pi-style architecture provides effective suppression of electromagnetic interference across multiple lines.
• Wettable flank design facilitates optimal automatic optical inspection during manufacturing processes.

Applications

• Parallel interface data transmission systems requiring high-speed signal integrity
• Applications necessitating minimal wireless interference mitigation
• Automotive electronic modules requiring AEC-Q101 qualification

Procurement Notes

Verify that the specific part number suffix WT1G corresponds to the DFNW12 package with wettable flanks, distinct from standard DFN12 variants. Confirm AEC-Q101 automotive qualification status if required for the target application. Ensure compliance with RoHS and halogen-free specifications as stated in official documentation. Cross-reference the manufacturer's ordering information to validate availability and packaging quantities before procurement.

Selection Notes

Select this component when designing circuits that require simultaneous EMI filtering and ESD protection for up to six channels. The 110 MHz cutoff frequency and 74 Mbps data rate support are critical parameters for parallel interface applications. Consider the DFNW12 package dimensions for space-constrained PCB layouts. Verify thermal performance requirements given the exposed pad design for heat dissipation.

Part Context

This component belongs to onsemi's NUF series of integrated EMI/ESD filter arrays. It is an automotive-qualified variant (SZ prefix) of the NUF6401MN, specifically designed for environments requiring higher reliability and traceability. The series addresses the growing need for compact, multi-line protection solutions in modern electronic devices.

Replacement Considerations

The NUF6401MNT1G serves as a functional equivalent but utilizes a standard DFN12 package without wettable flanks. Verify if the AOI inspection requirement mandates the WT1G variant. No other direct substitutes are documented in the provided source material.
