AO4440L

Overview

The AO4440L 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 drain-source voltage of 60V and a continuous drain current of 5A at 25°C. Key electrical parameters include an on-resistance of less than 55mΩ at VGS=10V and less than 75mΩ at VGS=4.5V. It operates within a junction 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 as a Green Product option that is electrically identical to the standard AO4440.

Applications

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

Procurement Notes

Verify the specific ordering suffix 'L' against official Alpha & Omega Semiconductor documentation to confirm compliance with environmental specifications such as RoHS and Sony 259 standards. Ensure the component matches the SOIC-8 package dimensions and pinout configuration required for your PCB layout. Confirm that the application does not involve critical life support devices, as this product is qualified for the consumer market only.

Selection Notes

Select the AO4440L when a 60V N-Channel MOSFET with low gate charge is required for efficient switching performance. Consider its thermal resistance characteristics and power dissipation limits relative to the expected operating environment. Verify that the required continuous drain current of 5A meets the circuit demands under the specified ambient temperature conditions.

Part Context

This component belongs to the Alpha & Omega Semiconductor AO44xx series of N-Channel MOSFETs. These devices are engineered using trench technology to optimize conduction losses and switching speeds. The AO4440L variant shares electrical characteristics with the standard AO4440 but offers specific ordering options regarding environmental compliance.
