AOI403

Overview

The AOI403 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
Low gate resistance for efficient driving

Applications

High current load applications
Power management circuits
DC-DC converters

Procurement Notes

Verify the specific package variant required, as the datasheet covers both TO-252 (DPAK) and TO-251A (IPAK) configurations which may have distinct ordering suffixes or part numbers. Confirm that the procurement source provides the exact Alpha & Omega Semiconductor Inc. manufacturer marking to ensure authenticity and traceability against the official specification sheet.

Selection Notes

Select this component for designs requiring a robust P-Channel MOSFET with high current handling capabilities up to 70A. Consider the thermal performance characteristics when designing heat dissipation strategies, noting the difference in thermal resistance between the DPAK and IPAK packages. Ensure gate drive voltages align with the specified thresholds for optimal on-resistance performance.

Part Context

The AOI403 belongs to the AOD/AOI series of P-Channel MOSFETs from Alpha & Omega Semiconductor. It shares electrical similarities with the AOD403 but differs in packaging options. This series is designed for general-purpose power switching applications where low conduction losses and fast switching speeds are critical requirements.
