NUF3102MUTAG

Overview

The NUF3102MUTAG is a unidirectional transient voltage suppression diode and EMI filter from onsemi, housed in an 8-lead UDFN package. It features three channels with a working voltage of 5 V and a breakdown voltage of 6 V. The device integrates a C-R-C Pi filter circuit with resistance values of 47 Ohms and 100 Ohms, alongside a capacitance of 13 pF per line. Diode capacitance is specified at 16 pF. It provides electrostatic discharge protection rated at 14 kV (contact) and 15 kV (air gap). The component operates within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a third-order low-pass C-R-C Pi filter circuit for effective electromagnetic interference attenuation.
• Provides robust electrostatic discharge protection compliant with IEC standards for contact and air gap discharges.
• Designed for high-speed data lines with low capacitance to minimize signal distortion.
• Utilizes a compact surface-mount UDFN-8 package suitable for space-constrained portable electronics.

Applications

• Protection of USB 2.0 and 3.0 data interfaces
• Guarding HDMI and DisplayPort connections
• Shielding high-speed serial communication lines

Procurement Notes

Verify the specific suffix 'AG' against the manufacturer's current datasheet to confirm material composition and compliance status. Ensure the ordering part number matches the required tape and reel or cut tape configuration. Cross-reference the UDFN-8 package dimensions with your PCB footprint library to guarantee mechanical compatibility during assembly.

Selection Notes

Select this component when simultaneous ESD protection and EMI filtering are required on 5 V data lines. The integrated passive components reduce the bill of materials compared to discrete solutions. Evaluate the 16 pF diode capacitance against your signal integrity requirements to ensure minimal insertion loss at target frequencies.
