Procurement Notes
Verify the exact datasheet revision and package marking against the manufacturer's official documentation before procurement. Confirm that the 20-V rating aligns with your circuit requirements, as some sources may reference similar models with different voltage ratings. Ensure the SO-8 package footprint matches your PCB layout specifications.
Selection Notes
Select this component when a 20-V N-Channel MOSFET with high current handling capability is required. Consider the SO-8 package constraints for thermal management. Compare the specific on-resistance values from the full datasheet against load requirements to ensure efficiency targets are met within the operating temperature range.
Part Context
This part belongs to Analog Power Inc.'s N-Channel MOSFET lineup, which includes variants with different voltage ratings such as the AM4404N (30-V) and AM4482N (80-V). These components share common design philosophies focusing on low on-resistance and fast switching for power management applications.
Replacement Considerations
Check for direct substitutes with identical 20-V ratings and SO-8 packaging. Verify pin compatibility and electrical parameters such as R_DS(on) and I_D before substitution.
