Single FETs, MOSFETs Procurement Notes
Verify the specific suffix 'L' if halogen-free compliance is required, as standard parts may differ. Confirm the exact package variant (TO-220F vs TO-220) matches the design footprint. Check for recent Product Change Notices (PCN) regarding subcontractor changes or specification updates before finalizing procurement.
Single FETs, MOSFETs Selection Notes
Select this component for designs requiring 500V blocking capability with moderate current handling up to 14A. Ensure the gate drive voltage supports the 10V threshold for optimal Rds(on) performance. Consider thermal management requirements given the 0.38Ω on-resistance at full load conditions.
Single FETs, MOSFETs Part Context
This part belongs to the AOT series of high-voltage MOSFETs by Alpha & Omega Semiconductor. It shares architectural similarities with the AOB14N50 and AOT14N50FD variants, differing primarily in packaging and specific electrical tolerances defined for offline power conversion topologies.
Single FETs, MOSFETs Replacement Considerations
Public confirmed substitutes include AOT14N50FD and AOB14N50. Verify pinout compatibility and thermal resistance values when substituting between different package types within the same family.
