AOZ8073DI

Overview

The AOZ8073DI is a second-order low-pass EMI/RFI filter manufactured by Alpha & Omega Semiconductor Inc. It utilizes an RC Pi topology with four independent channels, each configured with a 100 Ohm resistor and an 8 picofarad capacitor. Designed for data line protection in mobile devices, the component features an 8-UFDFN package with an exposed pad. The filter provides a cutoff frequency of 220 MHz and achieves -20 dB attenuation at 1 GHz, ensuring effective suppression of electromagnetic interference while maintaining signal integrity.

Feature Summary

• Integrates four independent low-pass filter channels within a single compact package
• Employs RC Pi topology to provide robust EMI and RFI suppression
• Optimized specifically for protecting data lines in mobile device applications

Applications

• Data line filtering in mobile devices
• EMI suppression for high-speed digital interfaces
• RFI protection in portable consumer electronics

Procurement Notes

Verify the specific suffix DI against the manufacturer's official datasheet to confirm pinout compatibility and thermal pad requirements. Ensure the selected variant matches the required 8-UFDFN package dimensions and exposed pad configuration for proper PCB mounting and heat dissipation. Cross-reference the part number with current production status documentation to avoid obsolete components.

Selection Notes

Select this component when designing circuits requiring multi-channel EMI filtering for mobile data lines. The integrated RC Pi structure simplifies layout compared to discrete components. Verify that the 100 Ohm resistance and 8 pF capacitance values align with the target data rate and impedance matching requirements of the specific interface being protected.

Part Context

This component belongs to Alpha & Omega Semiconductor's passive filtering portfolio, distinct from their active power management or semiconductor offerings. It addresses the growing need for compact, integrated noise suppression solutions in space-constrained mobile electronics where multiple data lines require simultaneous protection without increasing board footprint.

Replacement Considerations
