Applications

• Audio port protection in mobile devices
• ESD suppression for headphone jack circuits
• EMI filtering for digital audio interfaces

Procurement Notes

Verify the specific ordering suffix and tape/reel specifications against the official manufacturer datasheet prior to procurement. Confirm that the DFN-8 package dimensions align with the target PCB footprint requirements. Ensure compliance with RoHS directives as specified in the product documentation. Cross-reference the part number with the latest revision history to confirm availability status and manufacturing origin details.

Selection Notes

Select this component for applications requiring combined EMI attenuation and transient voltage suppression on differential audio lines. The low parasitic capacitance ensures minimal impact on audio signal integrity compared to standard TVS diodes. Evaluate the thermal performance within the DFN-8 package constraints for high-density board layouts. Consider the 12 V operating voltage rating when interfacing with various power supply rails in portable electronics.

Part Context

This device belongs to the NUF series of integrated ESD protection and EMI filters from onsemi. It is specifically engineered for consumer electronics where space constraints and signal purity are critical. The integration of passive filtering components with active protection elements reduces the overall bill of materials and simplifies the circuit design process for audio subsystems.
