Overview
The AM40N04-30D is a single N-channel silicon MOSFET manufactured by Analog Power Inc. It features a drain-source voltage (VDS) rating of 40 V and a continuous drain current (ID) of 33 A at ambient temperature. The device exhibits a maximum on-resistance (RDS(on)) of 32 mΩ. It is housed in a TO-252 surface-mount package with a thermal dissipation capacity of 50 W at ambient temperature.
Feature Summary
- Single N-channel silicon construction for power switching applications
- Low on-resistance characteristic to minimize conduction losses
- Surface-mount TO-252 package design for efficient thermal management
Applications
- DC-DC converter circuits
- Power supply load switches
- Motor control driver stages
Procurement Notes
Verify the manufacturer designation as Analog Power Inc. when sourcing this component. Confirm the specific suffix '30D' corresponds to the TO-252 package variant. Ensure compatibility with standard SMD reflow profiles. Cross-reference part numbers carefully to distinguish from similar voltage ratings or package types within the manufacturer's portfolio.
Selection Notes
Select this component for applications requiring a 40 V breakdown voltage and up to 33 A continuous current handling. The 32 mΩ on-resistance makes it suitable for low-loss power paths. The TO-252 package is appropriate for board-level mounting where moderate heat dissipation is required without additional heatsinking solutions.
Part Context
This component belongs to the category of single discrete N-channel MOSFETs designed for general-purpose power switching. It is distinct from high-voltage industrial variants or logic-level specific devices. The product line focuses on balancing voltage ratings with current capabilities for consumer and industrial electronics.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical parameters before considering any alternative components from other manufacturers.
