Selection Notes
Select this component for designs requiring robust N-channel switching with standard gate drive compatibility. Ensure thermal management accounts for the 1.7 K/W junction-to-mounting-base resistance. Verify that the application voltage remains below the 100 V limit and current stays within the 21.7 A continuous rating at the expected operating temperature.
Part Context
This part belongs to Nexperia's TrenchMOS standard level FET family. It is designed for high-performance automotive applications, qualifying under AEC-Q101. The DPAK package provides a balance of power handling and surface-mount convenience, suitable for general-purpose switching tasks in automotive systems.
Replacement Considerations
Check for direct replacements within the BUK7275 series or other Nexperia DPAK N-channel MOSFETs with matching 100 V ratings. Verify pinout compatibility and ensure thermal resistance characteristics are equivalent for direct substitution in existing footprints.
