Overview
The AO7404 is a surface-mount N-channel MOSFET from Alpha & Omega Semiconductor. It features a drain-source voltage (Vdss) of 20 V and a continuous drain current (Id) of 20 A at Vgs = 4.5 V. The device exhibits an on-resistance (Rds(on)) of less than 6 mΩ at Vgs = 4.5 V and less than 7.5 mΩ at Vgs = 2.5 V. Designed for efficient power switching, it utilizes advanced trench technology to minimize conduction losses in compact packages.
Feature Summary
- Combines advanced trench MOSFET technology with low resistance packaging
- Provides extremely low Rds(ON) for high efficiency
- Optimized for load switch applications
- Suitable for battery protection circuits
Applications
- Load switch implementations
- Battery protection systems
- DC-DC converter stages
Procurement Notes
Verify the specific package variant and tape/reel specifications against the official datasheet before procurement. Ensure that the ordering part number matches the required pin configuration and thermal characteristics. Confirm compliance with RoHS standards if applicable to your manufacturing process. Cross-reference the manufacturer's latest documentation to avoid obsolete stock issues.
Selection Notes
Select this component when a 20 V rating and 20 A continuous current capability are required. The low Rds(ON) values at both 4.5 V and 2.5 V gate drives make it suitable for logic-level control applications. Consider the thermal performance and package size constraints relative to the expected power dissipation in the target circuit design.
Part Context
Alpha & Omega Semiconductor specializes in power semiconductors, including MOSFETs and IGBTs. The AO7404 belongs to their portfolio of N-channel devices designed for high-efficiency power management. The company integrates design, wafer fabrication, and assembly testing to deliver reliable components for consumer and industrial electronics markets.
Replacement Considerations
Check for direct substitutes with identical 20 V/20 A ratings and comparable Rds(ON) specifications. Verify pin compatibility and package dimensions to ensure mechanical fit. Evaluate thermal resistance parameters to maintain equivalent heat dissipation capabilities in the existing layout.
