AOD502

Overview

The AOD502 is a 25V N-Channel AlphaMOS power MOSFET manufactured by Alpha & Omega Semiconductor. It utilizes advanced trench technology to achieve very low on-resistance and high current capability. The device features a maximum drain-source voltage of 25V, a continuous drain current of 46A at VGS=10V, and an on-resistance of less than 8mΩ at VGS=10V. It operates within a junction temperature range of -55°C to 175°C and is housed in a TO-252 (DPAK) surface-mount package.

Feature Summary

Very low RDS(on) at 4.5V gate-source voltage
Low gate charge for efficient switching
High current capability with robust thermal performance
100% UIS tested for avalanche ruggedness

Applications

DC/DC converters in computing
Isolated DC/DC converters in telecom
Isolated DC/DC converters in industrial applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status as required by your assembly standards. Check for any recent product change notices or lifecycle updates directly from Alpha & Omega Semiconductor before finalizing procurement plans.

Selection Notes

Select this component for low-voltage, high-current synchronous rectification or switching applications where low conduction loss is critical. Ensure the gate drive voltage supports the specified RDS(on) thresholds. Verify that the PCB layout accommodates the TO-252 package dimensions and provides adequate copper area for thermal dissipation given the junction-to-ambient resistance characteristics.
