Overview
The AO4404BL is an N-Channel Enhancement Mode Field Effect Transistor manufactured by Alpha & Omega Semiconductor. It features a 30V drain-source voltage rating and supports a continuous drain current of 8.5A at ambient temperature. The device utilizes advanced trench technology to achieve low on-resistance, specified as less than 28mΩ at VGS=10V and less than 43mΩ at VGS=4.5V. Packaged in an 8-SOIC format, it is designed for efficient power switching applications with standard RoHS compliance.
Feature Summary
- Utilizes advanced trench technology for optimized performance
- Provides low gate charge characteristics for efficient switching
- Designed for use as a load switch or in PWM applications
Applications
- Load switching circuits
- Pulse Width Modulation (PWM) control systems
- Power management modules requiring N-channel enhancement mode transistors
Procurement Notes
Verify the specific ordering suffix and package variant against the manufacturer's latest datasheet to ensure compatibility with design requirements. Confirm that the component meets all relevant environmental standards, such as RoHS, if required by the end product specifications. Cross-reference part numbers carefully to distinguish between electrically identical variants like the AO3404L.
Selection Notes
Select this component when a compact N-channel MOSFET with 30V capability and moderate current handling is required. Consider the 8-SOIC package constraints for thermal dissipation and PCB layout. Ensure the drive voltage aligns with the specified RDS(ON) thresholds for optimal efficiency in the target application circuit.
Part Context
This device belongs to the family of N-Channel Enhancement Mode Field Effect Transistors from Alpha & Omega Semiconductor. It shares electrical similarities with other models in the series, utilizing similar trench technology principles. The AO4404BL is distinct in its specific 8-SOIC packaging configuration while maintaining core performance metrics consistent with the manufacturer's general product line.
Replacement Considerations
The AO3404 and AO3404L are electrically identical to this device family but utilize TO-236 (SOT-23) packaging. Verify pinout compatibility and physical footprint differences before substituting. Other 30V N-channel MOSFETs in SOIC-8 packages may serve as alternatives if electrical parameters match.
