AOD4184L

Overview

The AOD4184L is a plastic encapsulated N-channel MOSFET manufactured by Alpha & Omega Semiconductors. It utilizes advanced trench technology to achieve low gate charge and excellent on-resistance. The device features a drain-source voltage (VDS) of 40V and a continuous drain current (ID) of 50A at VGS=10V. At VGS=10V, the maximum on-resistance (RDS(ON)) is less than 8mΩ, while at VGS=4.5V, it remains below 11mΩ. These characteristics make the component suitable for high-current load applications.

Feature Summary

Advanced trench technology design for optimized performance
Low gate charge capability for efficient switching
Excellent thermal resistance inherent to the DPAK package

Applications

High current load applications
Power management circuits requiring low on-resistance
Switching regulators utilizing 40V N-channel MOSFETs

Procurement Notes

Verify the manufacturer designation as Alpha & Omega Semiconductors or AOSMD when sourcing. Confirm the specific suffix 'L' corresponds to the described 40V, 50A specifications with RDS(ON) under 8mΩ at 10V. Ensure the package type matches the DPAK form factor required for the intended thermal and current handling needs.

Selection Notes

Select this component for designs requiring a 40V N-channel MOSFET capable of handling 50A continuous current. The low on-resistance values at both 10V and 4.5V gate drives offer flexibility in driver circuit design. The DPAK package provides necessary thermal dissipation for high-power scenarios.

Part Context

The AOD4184L belongs to the AOD4184 series from Alpha & Omega Semiconductors. This series employs advanced trench technology to deliver superior on-resistance and low gate charge. The devices are specifically engineered for high-current applications where efficient power switching and thermal management are critical requirements.
