Procurement Notes
Verify the specific suffix 'L' against the manufacturer's official datasheet to confirm pinout and electrical tolerances. Confirm RoHS compliance status and check for Product Change Notifications (PCN) regarding manufacturing site updates. Ensure the supplier provides traceability documentation consistent with Alpha & Omega Semiconductor standards.
Selection Notes
Select this component where a 700 V rating is required alongside moderate current handling capabilities. The TO-263 package facilitates efficient heat transfer compared to smaller form factors. Evaluate the 450 mΩ Rds(on) against system efficiency targets at the intended operating current levels.
Part Context
This part belongs to the AOB series of N-channel MOSFETs from Alpha & Omega Semiconductor. The series focuses on high-voltage solutions utilizing advanced silicon processes. The AOB450A70L specifically targets applications requiring reliable switching performance in compact surface-mount configurations.
Replacement Considerations
Check for direct substitutes such as the AOB450A70L variant or other 700 V D2PAK MOSFETs from the same manufacturer. Verify that any replacement matches the 700 V Vdss, 11 A Id, and 450 mΩ Rds(on) specifications exactly.
