AOD403

Overview

The AOD403 is a P-Channel Enhancement Mode Field Effect Transistor manufactured by Alpha & Omega Semiconductor Inc. It utilizes advanced trench technology to deliver low on-resistance and gate charge. The device features a drain-source voltage of -30V and a continuous drain current of -70A at VGS=-20V. On-resistance is less than 6.2mΩ at VGS=-20V and less than 8mΩ at VGS=-10V. It is available in TO-252 (DPAK) and TO-251A (IPAK) packages, with junction temperatures ranging from -55°C to 175°C.

Feature Summary

Advanced trench technology for excellent on-resistance and low gate charge
High thermal resistance suitable for high current load applications
Guaranteed avalanche capability with 100% UIS testing

Applications

High current load applications
Offline power supply designs
AC-DC converter circuits

Procurement Notes

Verify the specific package variant required, as the datasheet covers both TO-252 (DPAK) and TO-251A (IPAK) configurations with distinct electrical parameters. Confirm that the ordering suffix matches the desired package type. Ensure compliance with RoHS standards if applicable. Review the manufacturer's terms and conditions regarding product liability and specification changes before finalizing procurement.

Selection Notes

Select this component for applications requiring robust P-Channel MOSFET performance with high current handling capabilities. Consider the thermal characteristics and package limitations when designing heat dissipation strategies. Evaluate the gate drive requirements against the specified on-resistance thresholds to ensure optimal switching efficiency and minimize power loss during operation.

Part Context

This part belongs to the AOD series of P-Channel MOSFETs from Alpha & Omega Semiconductor. The series is designed for general-purpose power switching applications. The AOD403 specifically targets high-current scenarios where low on-resistance and fast switching speeds are critical for system efficiency and thermal management.

Replacement Considerations

Check for electrically identical alternatives such as the AOD403L, which shares the same specifications but may differ in environmental ordering options. Verify pinout compatibility and thermal resistance values when substituting with components from other manufacturers.
