Procurement Notes
Verify the component matches the exact Diodes Incorporated part number DMTH48M3SFVWQ-13. Confirm the datasheet revision is DS42273 Rev. 3 - 2 or later. Ensure the package type is PowerDI3333-8/SWP (Type UX). Validate that the supplier provides traceability documentation required for automotive-grade components.
Selection Notes
Select this component when a 40V rating and low on-resistance are required for high-current switching. The 175°C operating range suits high-temperature environments. Verify gate drive voltage compatibility with the specified threshold characteristics. Consider thermal management solutions based on the provided junction-to-case resistance values.
Part Context
This MOSFET belongs to the DMTH series designed for automotive use. It utilizes silicon technology within a lead-free, halogen-free PowerDI package. The device meets stringent reliability standards including unclamped inductive switching testing.
Replacement Considerations
Consult official manufacturer substitution lists for verified equivalents. Do not assume pin-compatible alternatives without verifying electrical parameters and package dimensions against the original specifications.
