AO4914L

Overview

The AO4914L is a dual N-channel MOSFET integrated with a Schottky diode, manufactured using advanced trench technology. It features a 30V drain-source voltage rating and an 8A continuous drain current at VGS=10V. The on-resistance is less than 20.5mΩ at VGS=10V and 28mΩ at VGS=4.5V. The device includes ESD protection and has undergone 100% UIS and Rg testing. The Schottky diode offers a forward voltage of less than 0.5V at 1A. It is housed in an SOIC-8 package.

Feature Summary

Advanced trench technology provides low on-resistance and gate charge for high efficiency.
Integrated Schottky diode boosts efficiency by acting as a synchronous rectifier.
ESD protected design ensures robustness against electrostatic discharge events.
Compact packaging combines two MOSFETs and a diode for space-saving applications.

Applications

DC-DC converters
Synchronous rectification circuits
Power management modules

Procurement Notes

Verify the specific suffix 'L' against the official datasheet to confirm if it denotes a distinct variant or standard packaging configuration. Ensure the component meets consumer market qualification standards as critical life support applications are not authorized. Confirm thermal resistance values match your board design requirements.

Selection Notes

Select this component for applications requiring compact dual N-channel MOSFET solutions with integrated body diodes. Consider the 30V rating and 8A current capacity for low-voltage power stages. Evaluate the thermal performance based on your PCB copper area and ambient temperature conditions.

Part Context

The AO4914L belongs to Alpha & Omega Semiconductor's lineup of dual MOSFET arrays. It utilizes trench technology to achieve low RDS(ON) and fast switching speeds. The integration of a Schottky diode distinguishes it from standard dual MOSFET packages, offering enhanced performance in synchronous rectification topologies.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical parameters before considering any alternative components.
