AO3403

Overview

The AO3403 is a P-Channel Enhancement Mode Field Effect Transistor manufactured by Alpha & Omega Semiconductor. It utilizes advanced trench technology to deliver low gate charge and excellent on-resistance characteristics. The device is housed in an SOT-23 surface-mount package with three pins. Key electrical parameters include a drain-source voltage of -30V, a continuous drain current of -2.6A at VGS=-10V, and a maximum power dissipation of 1.4W at 25°C ambient temperature. The junction temperature range spans from -55°C to 150°C.

Feature Summary

Advanced trench technology provides low gate charge and excellent RDS(ON).
Suitable for use as a load switch or in PWM applications.

Applications

Load Switch
PWM Applications

Procurement Notes

Verify the specific datasheet revision and ordering suffixes directly with Alpha & Omega Semiconductor or authorized distributors. Confirm that the component meets RoHS and Sony 259 specifications if required. Ensure the sourcing channel provides valid traceability documentation. Cross-reference the part number against the manufacturer's official active product list to confirm current availability status before finalizing procurement plans.

Selection Notes

Select this component when a compact P-Channel MOSFET is required for low-voltage switching applications. The SOT-23 package offers space efficiency for portable devices. Evaluate the thermal resistance requirements based on the specific board design, as the junction-to-ambient rating depends on copper area and airflow conditions. Verify that the gate drive voltage aligns with the specified on-resistance thresholds for optimal performance.

Part Context

This component belongs to the Alpha & Omega Semiconductor P-Channel MOSFET family. It is designed for general-purpose switching tasks where size and efficiency are priorities. The device is electrically identical to the AO3403L variant, which represents a green product ordering option. Both versions share the same pinout and electrical specifications within the SOT-23 form factor.
