EMI9404MUTAG

Overview

The EMI9404MUTAG is a four-channel EMI filter array with integrated ESD protection, manufactured by onsemi. It operates at a working voltage of 5 V and utilizes a unidirectional configuration within a UDFN-8 surface-mount package measuring 1.7 x 1.35 x 0.5 mm. Key electrical specifications include a diode capacitance of 24 pF, a clamp voltage of 20 V, and a peak pulse current rating of 16 A. The device withstands electrostatic discharge voltages of 14 kV (contact) and 16 kV (air gap). It functions reliably within an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates four-channel EMI filtering with simultaneous ESD protection for high-speed data lines
• Engineered to safeguard against ESD, EFT, and lightning-induced transients
• Utilizes a compact UDFN-8 package suitable for space-constrained designs

Applications

• Protection of high-speed data lines
• ESD and surge suppression in portable electronics
• EMI filtering for communication interfaces

Procurement Notes

Verify component status carefully as the EMI9404MUTAG is scheduled for obsolescence and will be discontinued by the manufacturer. Confirm availability through authorized distributors or secondary market suppliers, noting that lead times may vary significantly. Ensure final design decisions account for long-term supply chain stability given the end-of-life designation.

Selection Notes

Select this component when designing circuits requiring combined EMI attenuation and robust ESD protection for 5 V data lines. The low capacitance value supports high-speed signal integrity, while the unidirectional polarity suits specific line configurations. Evaluate the UDFN-8 footprint compatibility during PCB layout to ensure proper thermal and mechanical integration.

Part Context

This part belongs to the EMI940 series from onsemi, designed specifically for complex array configurations. It serves as an analog and mixed-signal solution for protecting sensitive inputs. The device integrates multiple functions into a single small outline package, reducing board space compared to discrete components.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation due to the end-of-life status. Engineers should consult official onsemi resources for potential next-generation replacements or equivalent family members.
