Overview
The AO3404 is an N-Channel Enhancement Mode Field Effect Transistor manufactured by Alpha & Omega Semiconductor. It utilizes advanced trench technology to deliver excellent R DS(ON) and low gate charge characteristics. The device is housed in a TO-236 (SOT-23) package. Key electrical parameters include a Drain-Source Voltage (V DS) of 30V, a continuous Drain Current (I D) of 5.8A at V GS = 10V, and a maximum Gate-Source Voltage (V GS) of ±20V. The on-resistance is specified as less than 28mΩ at V GS = 10V and less than 43mΩ at V GS = 4.5V.
Feature Summary
- Advanced trench technology for optimized performance
- Low gate charge capability
- Excellent on-resistance characteristics
Applications
- Load switch applications
- PWM applications
Procurement Notes
Verify the specific ordering suffix when purchasing. The AO3404L is a Green Product option that is electrically identical to the standard AO3404. Confirm RoHS compliance status, as the standard product meets ROHS specifications while the L variant offers an eco-friendly alternative. Ensure the component matches the required SOT-23 package dimensions and lead configuration for your PCB layout.
Selection Notes
Select this component for circuits requiring a compact N-channel MOSFET with low on-resistance. The TO-236 package suits space-constrained designs. Consider the gate drive voltage requirements, as R DS(ON) varies between 10V and 4.5V conditions. Verify thermal management needs based on the 1.4W power dissipation rating and operating temperature range of -55°C to 150°C.
Part Context
Alpha & Omega Semiconductor produces this device using trench technology to enhance efficiency in power management solutions. The AO3404 belongs to a family of N-Channel Enhancement Mode FETs designed for general-purpose switching. It serves as a standard product compliant with environmental regulations, offering reliability for consumer and industrial electronics.
Replacement Considerations
The AO3404L is an electrically identical alternative available as a Green Product option. Other manufacturers may offer compatible 30V N-Channel MOSFETs in SOT-23 packages, but direct substitution requires verification of pinout compatibility and exact electrical parameter matching.
