- Designed for surface-mount integration to optimize board space
- Supports high-voltage operation with robust thermal characteristics
Applications
- DC/DC conversion circuits
- Power management systems
- General-purpose switching applications
Procurement Notes
Verify the specific datasheet version from Analog Power Inc. to confirm exact electrical parameters and thermal resistance values. Ensure the 8-SOIC package footprint matches your PCB design requirements. Cross-reference the part number with official distributor catalogs to confirm availability and authenticity before procurement.
Selection Notes
Select this component when a 100 V N-Channel MOSFET is required for surface-mount implementations. Consider the 9 A current rating and 3.1 W power dissipation limits against your thermal management strategy. Verify that the SO-8 package dimensions align with your assembly constraints and that the switching speed meets your application's timing requirements.
Part Context
This component belongs to the Analog Power Inc. MOSFET family, which includes various voltage and current ratings. Similar parts like the AM4490N share the 100 V specification but may differ in current handling or package type. The series targets industrial and consumer electronics markets requiring reliable discrete power switching solutions.
Replacement Considerations
Check for direct pin-compatible substitutes within the same manufacturer's lineup. Verify that alternative N-Channel MOSFETs meet or exceed the 100 V breakdown voltage and 9 A current capacity. Ensure the replacement package maintains the 8-SOIC form factor for seamless integration.
