Overview
The AM7442N is an N-Channel MOSFET manufactured by Analog Power Inc., designed for surface-mount applications. It features a Drain-Source Voltage (V_DS) of 40 V and a continuous Drain Current (I_D) of 20 A at ambient temperature. The device utilizes low R_DS(on) trench technology to minimize conduction losses. It is housed in an 8-DFN package with dimensions of 5.2x5.55 mm, offering low thermal impedance for efficient heat dissipation.
Feature Summary
- Low on-resistance achieved through trench technology
- Fast switching speed capabilities
- Low thermal impedance design
Applications
- White LED boost converters
- Automotive systems
- Industrial DC/DC conversion circuits
Procurement Notes
Verify the specific datasheet version from Analog Power Inc. to confirm exact electrical characteristics and thermal ratings. Ensure the ordering information matches the required package style and tape/reel specifications for automated assembly processes.
Selection Notes
Select this component for designs requiring a 40 V rating with high current handling up to 20 A. Consider the 8-DFN footprint for space-constrained PCB layouts. Evaluate thermal management requirements based on the specified power dissipation limits under steady-state conditions.
Part Context
This part belongs to the single FET and MOSFET category from Analog Power Inc. It is comparable to other N-Channel MOSFETs in similar voltage and current ranges, such as the AM4482N which offers higher voltage ratings but lower current capacity in a similar package configuration.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing circuit designs before considering alternative components from other manufacturers.
