Overview
The AO3424 is an N-Channel Enhancement Mode Field Effect Transistor manufactured by Alpha & Omega Semiconductor Inc. It utilizes advanced trench technology to deliver excellent RDS(ON) and very low gate charge, enabling operation with gate voltages as low as specified in the datasheet. The device is housed in a surface-mount SOT-23-3 package. Key electrical parameters include a drain-source voltage (Vds) of 30 V, a continuous drain current (Ids) of 3.8 A at ambient temperature, and a power dissipation of 1.4 W at Ta. Additional characteristics include a rise time of 1.5 ns and an input capacitance (Ciss) of 270 pF measured at Vds = 15 V.
Feature Summary
- Advanced trench technology for optimized on-resistance
- Low gate charge for efficient switching performance
- Compatible with low gate drive voltage applications
Applications
- Power management circuits
- Load switching applications
- DC-DC converter output stages
Procurement Notes
Verify the specific manufacturer part number against official Alpha & Omega Semiconductor documentation to confirm exact electrical ratings and package type. Ensure the component matches the required N-Channel configuration and SOT-23-3 footprint for your design. Cross-reference technical specifications directly with the latest datasheet to avoid discrepancies from generic listings.
Selection Notes
Select this component when a compact N-Channel MOSFET with 30 V rating and approximately 3.8 A continuous current capability is required. The SOT-23-3 package suits space-constrained designs. Verify that the thermal requirements align with the 1.4 W dissipation limit under your specific operating conditions and ambient temperature constraints.
Part Context
This component belongs to the single FETs and MOSFets category from Alpha & Omega Semiconductor Inc. It is designed for general-purpose switching applications requiring small form factors. The AO3424 is distinct from P-Channel variants like the AO3401A within the same product family, offering complementary functionality for high-side or low-side switching topologies.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Engineers should consult official distributor databases or manufacturer cross-reference tools to identify compatible alternatives based on matching electrical parameters and package dimensions.
