Procurement Notes

Verify the exact part number against official onsemi documentation to ensure compatibility with specific design requirements. Confirm that the integrated common mode filter characteristics align with the target application's impedance and attenuation needs. Check for any specific handling or storage instructions provided in the datasheet to maintain component integrity during assembly.

Selection Notes

Select this component when both ESD protection and common mode noise suppression are required for differential pairs. Ensure the operating voltage matches the system's 3.3 V logic level. Consider the XDFN-10 package size constraints and thermal performance relative to the PCB layout. Verify that the capacitance values do not degrade signal integrity for the intended data rate.

Part Context

This component belongs to the EMI814x series from onsemi, which focuses on protecting high-speed interfaces. It combines passive filtering elements with active ESD diodes to offer comprehensive protection in a single small footprint. This integration helps reduce board space and simplifies the bill of materials for designers managing multiple protection requirements.

Replacement Considerations

Check for direct substitutes within the EMI814x family, such as variants with different pin counts or package sizes. Ensure any replacement maintains the same 3.3 V operating voltage and 15 kV ESD rating. Verify that the alternative component's common mode impedance and DC resistance meet the circuit's signal transmission requirements.
