AOB66620L

Overview

The AOB66620L is a 60V N-Channel AlphaSGT™ Trench Power MOSFET manufactured by Alpha & Omega Semiconductor Inc. It features a TO-263 (D2PAK) surface-mount package with a minimum order quantity of 800 units per tape and reel. Key electrical parameters include a drain-source breakdown voltage (BVDSS) of 60V, a continuous drain current (ID) of 57A at VGS=10V, and a maximum static drain-source on-resistance (RDS(ON)) of less than 8.5mΩ at VGS=10V and 11mΩ at VGS=8V. The device has a total gate charge (Qg) of 25nC at VGS=10V, a maximum junction-to-case thermal resistance (RθJC) of 2.5°C/W, and operates within a junction temperature range of -55°C to 150°C.

Feature Summary

• Utilizes AlphaSGT™ trench power MOSFET technology for low RDS(ON) and excellent gate charge performance.
• Features an optimized product figure of merit (FOM) combining low gate charge and low on-resistance.
• Includes 100% UIS (Unclamped Inductive Switching) testing and 100% Rg (Gate Resistance) testing.

Applications

• Synchronous rectification in switch-mode power supplies (SMPS)
• ATX power supplies
• Gaming power supplies

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the base part number covers both TO-220 tube and TO-263 tape/reel variants. Confirm that the component meets RoHS and halogen-free compliance requirements for your assembly process. Ensure the design accounts for the specified minimum order quantity associated with the tape and reel packaging format.

Selection Notes

Select this component for applications requiring high efficiency in synchronous rectification due to its low RDS(ON) and fast switching characteristics. Consider the TO-263 package for surface-mount designs needing robust thermal dissipation capabilities. Evaluate the gate charge specifications against driver capabilities to ensure optimal switching speeds and minimize switching losses in high-frequency operation.

Part Context

This component belongs to the AlphaSGT™ series from Alpha & Omega Semiconductor Inc., designed for general-purpose power switching applications. It serves as a surface-mount alternative to through-hole variants like the AOT66620L, offering similar electrical performance in a compact D2PAK form factor suitable for automated PCB assembly processes.

Replacement Considerations

The AOT66620L is functionally equivalent to the AOT66620L when accounting for package differences. Verify pinout compatibility and thermal resistance values when substituting between different package types within the same electrical specification family.
