AO3404A

Overview

The AO3404A is an N-Channel Enhancement Mode Field Effect Transistor manufactured by Alpha & Omega Semiconductor. It utilizes advanced trench technology to achieve excellent RDS(ON) and low gate charge characteristics. The device is housed in a SOT-23 package with three pins. Key electrical parameters include a Drain-Source Voltage (VDS) of 30V, a continuous Drain Current (ID) of 5.8A at VGS=10V, and a maximum Gate-Source Voltage (VGS) of ±20V. The on-resistance is less than 25mΩ at VGS=10V and less than 35mΩ at VGS=4.5V. The component supports a junction temperature range from -55°C to 150°C.

Feature Summary

Advanced trench technology provides excellent on-resistance and low gate charge.
Suitable for use as a load switch or in PWM applications.
Separated source leads allow for Kelvin connection to bypass source inductance.

Applications

Load switching
PWM applications

Procurement Notes

Verify the specific datasheet revision and manufacturer documentation when sourcing components. Confirm that the ordering suffix matches the exact electrical specifications required for the design. Ensure compliance with consumer market qualifications as stated in the official documentation. Cross-reference pinout configurations to guarantee correct integration into the target circuit layout.

Selection Notes

Select this component for designs requiring a compact N-channel MOSFET with low on-resistance. Consider the thermal resistance values and power dissipation limits relative to the operating environment. Evaluate the gate charge requirements against the driving capability of the control signal source. Verify that the voltage and current ratings exceed the maximum expected operational stresses.

Part Context

This part belongs to the family of N-Channel Enhancement Mode Field Effect Transistors produced by Alpha & Omega Semiconductor. These devices are designed for general-purpose switching applications where low on-resistance and fast switching speeds are beneficial. The SOT-23 package offers a small footprint suitable for space-constrained printed circuit board layouts.

Replacement Considerations

Check for electrically identical alternatives such as the AO3404 or AO3404L, which share similar specifications. Verify pin compatibility and thermal performance before substituting with parts from other manufacturers.
