AO4476AL

Overview

The AO4476AL is a 30V N-Channel Enhancement Mode Field Effect Transistor manufactured by Alpha & Omega Semiconductor. It utilizes advanced trench MOSFET technology to achieve extremely low on-resistance, making it suitable for high-side switching in switch-mode power supplies and general-purpose applications. The device features a continuous drain current of 15A at VGS=10V, with an on-resistance of less than 7.7mΩ at VGS=10V and less than 10.8mΩ at VGS=4.5V. It is housed in an SOIC-8 package.

Feature Summary

Advanced trench MOSFET technology provides extremely low on-resistance
Suitable for use as a high side switch in SMPS and general purpose applications
100% UIS tested for reliability

Applications

High side switch in Switch-Mode Power Supplies (SMPS)
General purpose switching applications

Procurement Notes

Verify the specific ordering suffix 'L' against official manufacturer documentation to confirm if it denotes a Green Product option or other variant characteristics, as datasheets may list standard and alternative suffixes separately. Confirm RoHS compliance status directly from the supplier's certification documents prior to procurement.

Selection Notes

Select this component based on its 30V drain-source voltage rating and 15A continuous drain current capability. Consider the low on-resistance values at both 10V and 4.5V gate drive voltages for efficiency requirements. Ensure the thermal management design accounts for the junction-to-ambient resistance specified in the datasheet.

Part Context

The AO4476A belongs to the AO44 series of N-Channel MOSFETs from Alpha & Omega Semiconductor. This series is characterized by the use of advanced trench technology to minimize on-resistance while maintaining robust avalanche capabilities. The AO4476AL shares electrical specifications with the standard AO4476A.

Replacement Considerations

The AO4476A is electrically identical to the AO4476AL according to manufacturer data. Verify pinout compatibility and package dimensions (SOIC-8) when substituting with other 30V N-Channel MOSFETs from different manufacturers.
