AON6918

Overview

The AON6918 is a dual asymmetric N-channel MOSFET manufactured by Alpha & Omega Semiconductor Inc. It features a 25V drain-source voltage rating and is housed in an 8-DFN package. The device integrates two independent N-channel FETs within a single surface-mount component, designed for efficient power switching applications requiring compact form factors.

Feature Summary

• Dual asymmetric configuration integrating two N-channel MOSFETs
• Low voltage operation rated at 25V
• Compact surface-mount packaging

Applications

• Power management circuits
• DC-DC converter modules
• Battery protection systems

Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to ensure correct pinout and thermal characteristics. Confirm RoHS compliance status with the supplier prior to ordering. Ensure the selected package variant matches the PCB footprint requirements for reliable soldering and thermal dissipation.

Selection Notes

Select this component for designs requiring dual N-channel switching in a minimal footprint. Evaluate the thermal resistance of the 8-DFN package against the expected current load. Ensure gate drive voltages are compatible with the threshold specifications for optimal switching performance.

Part Context

This part belongs to the AON69xx series of low-voltage MOSFETs from Alpha & Omega Semiconductor. It is distinct from the AOB66918L, which is a single high-current device in a TO-263 package. The AON6918 focuses on integration and space-saving for lower voltage applications.

Replacement Considerations

Check for direct substitutes such as the AON6912 or AON6910 if pin compatibility is required. Verify that alternative parts maintain the 25V rating and dual asymmetric topology before implementation.
