Overview
The AM7340N is an N-Channel MOSFET from Analog Power Inc., rated for a drain-source voltage of 40 V. It supports a continuous drain current of 21 A at ambient temperature and dissipates up to 3.5 W of power under the same conditions. The device utilizes a DFN3x3-8L surface-mount package, designed for compact circuit layouts.
Feature Summary
- N-Channel configuration optimized for low-voltage switching applications
- Surface-mount DFN3x3-8L package for space-constrained designs
- Capable of handling 21 A continuous drain current
Applications
- Power routing circuits
- Motor drives
Procurement Notes
Verify the specific datasheet revision (DS_AM7340N_1A) against your design requirements. Confirm RoHS compliance status and lead-free characteristics with the supplier. Ensure the DFN3x3-8L footprint matches your PCB layout constraints before finalizing procurement.
Selection Notes
Select this component when a 40 V N-Channel MOSFET is required for motor or power routing applications. The 21 A current rating suits moderate power loads. Verify thermal management needs given the 3.5 W dissipation limit in the small DFN3x3 package.
Part Context
This part belongs to Analog Power Inc.'s single FET and MOSFET product line. It complements other devices like the AM7341P P-Channel variant within the same voltage family, offering complementary switching solutions for bridge configurations.
Replacement Considerations
Cross-reference with AM7341P for complementary P-Channel needs. Verify pinout compatibility and electrical parameters against other 40 V N-Channel DFN3x3 MOSFETs from different manufacturers if substitution is necessary.
