Procurement Notes
Verify the specific package variant required, as the datasheet covers TO252 (AOD514), TO251A (AOI514), and TO251B (AOY514). Confirm RoHS compliance status and ensure the supplier provides official Alpha & Omega Semiconductor documentation to validate electrical parameters against the Rev.6.1 datasheet specifications.
Selection Notes
Select this component for applications requiring high current handling within a 30V system. The low on-resistance at both 10V and 4.5V gate drive voltages makes it suitable for logic-level control interfaces. Ensure thermal management aligns with the junction-to-case resistance limits provided in the datasheet.
Part Context
This part belongs to the AlphaMOS series from Alpha & Omega Semiconductor Inc., designed for general-purpose power switching. The AOD514 specifically utilizes the TO252 DPAK surface-mount package, offering a compact solution for board space-constrained designs while maintaining robust thermal performance.
Replacement Considerations
Compatible variants include AOI514 (TO251A IPAK) and AOY514 (TO251B short lead IPAK). These share identical electrical specifications but differ in physical package dimensions and pinout orientation.
