Overview
The AOD21357 is a surface-mount P-channel MOSFET from Alpha & Omega Semiconductor, housed in a TO-252 (DPAK) package. It features a drain-source voltage of -30V and a continuous drain current of -70A at case temperature of 25°C. The device utilizes advanced trench technology to achieve a low on-resistance of less than 8mΩ at VGS=-10V and less than 13mΩ at VGS=-4.5V. It supports a maximum junction temperature of 150°C and includes 100% UIS and Rg testing.
Feature Summary
- Advanced trench technology for low on-resistance
- High current capability with 100% UIS testing
- RoHS and halogen-free compliant construction
Applications
- Notebook AC-in load switch
- Battery protection charge/discharge circuits
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact packaging format, such as tape and reel or tube quantities. Ensure compliance requirements match project specifications. Confirm that the component status remains active for new designs before finalizing procurement plans.
Selection Notes
Select this component for applications requiring high current handling in a compact surface-mount form factor. Evaluate thermal management needs based on the junction-to-case resistance. Verify gate drive voltage compatibility with the specified on-resistance thresholds for optimal efficiency.
Part Context
This part belongs to the AOD21 series of P-channel MOSFETs manufactured by Alpha & Omega Semiconductor. It is designed for power switching applications where low conduction losses and robust avalanche performance are critical. The TO-252 package provides efficient heat dissipation capabilities.
Replacement Considerations
Check datasheets for alternative P-channel MOSFETs with similar -30V ratings and comparable on-resistance values. Ensure pinout compatibility and thermal characteristics align with existing board designs.
