Overview
The AOD418 is an N-channel enhancement mode MOSFET manufactured by Alpha & Omega Semiconductor Inc. It features a 30V drain-source voltage rating and supports continuous drain currents of 13.5A at ambient temperature and 36A at case temperature. The device utilizes a TO-252 (DPAK) surface-mount package with a maximum power dissipation of 2.5W at ambient conditions and 50W at case temperature. Key electrical characteristics include a gate charge of 24nC at 10V, an input capacitance of 1380pF at 15V, and a threshold voltage maximum of 2.5V at 250μA. The component operates within a junction temperature range of -55°C to 175°C.
Feature Summary
- N-channel enhancement mode construction for efficient switching applications
- Low on-resistance performance optimized for high-current handling
- Robust thermal management capabilities via direct die attach to the lead frame
- Lead-free packaging compliant with RoHS standards
Applications
- DC-DC converter circuits requiring low-side switching
- Power management modules in portable electronic devices
- Motor control interfaces for small DC motors
Procurement Notes
Verify the specific ordering suffix to confirm the exact tape and reel quantity or cut tape configuration, as standard packaging may vary by distributor. Ensure the requested part number matches the TO-252-3 physical footprint. Confirm RoHS compliance status if required for specific regulatory environments. Check for any recent product change notices regarding marking or material composition updates from the manufacturer.
Selection Notes
Select this component when a 30V N-channel MOSFET is required in a DPAK package. Compare the 7.5mΩ on-resistance at 10V gate drive against alternative parts to ensure compatibility with existing driver logic levels. Evaluate the thermal resistance requirements based on whether the application relies on ambient cooling or heatsink attachment to the exposed pad. Verify that the 2.5V threshold voltage aligns with the system's minimum gate drive voltage.
Part Context
The AOD418 belongs to the AOx418 series of power MOSFETs from Alpha & Omega Semiconductor. This series is designed for general-purpose power switching applications where moderate voltage ratings and high current density are necessary. The TO-252 package provides a balance between thermal performance and board space efficiency, making it suitable for consumer electronics and industrial control systems.
Replacement Considerations
The AOD418 is functionally related to the AOD4185, which is a P-channel variant in the same package family. Direct substitution requires matching channel type and voltage ratings. Verify pinout compatibility and thermal characteristics before replacing with other N-channel MOSFETs in the TO-252 package.
