AOZ5039QI

Overview

The AOZ5039QI is a single-phase power driver module manufactured by Alpha & Omega Semiconductor. It integrates MOSFETs into a compact 31-PowerVFQFN package, rated for 50 A continuous current. The component is designed for surface-mount installation and complies with RoHS3 standards. It carries an MSL rating of 1 and an ECCN classification of EAR99. The device is currently marked as not recommended for new designs.

Feature Summary

• Integrates single-phase MOSFET power stage within a modular package
• Supports high-current operation up to 50 A
• Utilizes 31-PowerVFQFN surface-mount footprint

Applications

• High-current DC-DC conversion stages
• Power distribution modules requiring integrated switching elements
• Compact power supply designs utilizing single-phase topologies

Procurement Notes

Verify the obsolete status before integration, as the manufacturer indicates this part is not recommended for new designs. Confirm availability through authorized distributors, noting that standard packaging quantities may apply. Ensure compliance with RoHS3 requirements matches project specifications. Check for potential minimum order quantity restrictions imposed by suppliers due to limited production support.

Selection Notes

Select this module when a pre-integrated single-phase MOSFET solution is required to reduce board space and simplify thermal management. The 50 A rating suits applications needing substantial current handling in a small form factor. Consider the 31-PowerVFQFN package constraints for PCB layout. Evaluate alternative active parts if long-term supply assurance is critical for the product lifecycle.

Part Context

This component belongs to the AOZ5039 series from Alpha & Omega Semiconductor, focusing on integrated power driver modules. It shares the 31-PowerVFQFN package and 50 A current capability with siblings like the AOZ5038QI and AOZ5636QI. These modules consolidate power switching elements to streamline design processes for high-density power electronics.

Replacement Considerations

The AOZ5038QI serves as a confirmed substitute with identical electrical ratings and package dimensions. Verify pinout compatibility and thermal characteristics before swapping. Other series members like the AOZ5636QI offer similar configurations but require specific validation against the AOZ5039QI specifications.
