AO4440

Overview

The AO4440 is a 60V N-Channel Enhancement Mode Field Effect Transistor manufactured by Alpha & Omega Semiconductor. It utilizes advanced trench technology to deliver low on-resistance and gate charge, making it suitable for load switch and PWM applications. The device features a maximum continuous drain current of 5A at 25°C ambient temperature and a pulsed drain current of 20A. Key electrical parameters include a maximum RDS(ON) of 55mΩ at VGS=10V and 75mΩ at VGS=4.5V. The component operates within a junction and storage temperature range of -55°C to 150°C.

Feature Summary

Advanced trench technology provides excellent on-resistance and low gate charge characteristics.
Designed specifically for use as a load switch or in pulse-width modulation (PWM) applications.
Manufactured with 100% UIS (Unclamped Inductive Switching) testing and 100% Rg (Gate Resistance) testing.

Applications

Load switching circuits
Pulse-width modulation (PWM) control systems

Procurement Notes

Verify the specific datasheet revision and manufacturing lot details upon procurement. Confirm that the received components match the SOIC-8 package outline and pin configuration provided in the official documentation. Ensure compliance with the consumer market qualification status and verify that the application does not involve life support devices or systems, as such uses are explicitly unauthorized by the manufacturer.

Selection Notes

Select this component when a 60V N-channel MOSFET with moderate current handling capabilities is required for compact surface-mount designs. Consider the thermal resistance values and power dissipation limits relative to the expected operating environment. Evaluate the gate charge specifications against the driving circuit's capability to ensure efficient switching performance in the intended application.
