The attached MDD datasheet conflicts with the catalog description on current, power dissipation, and on-resistance. I’ll make that discrepancy explicit and distinguish pin-compatible alternatives from electrically interchangeable replacements.
The MDD 2N7002 is an enhancement-mode N-channel MOSFET in a three-terminal SOT-23 package, with a 60 V absolute maximum drain-source rating. A practical use is a low-side small-load switch controlled by a GPIO or gate driver; the source connects to ground and the drain connects to the load return, following the low-side topology described in TI's MOSFET design guide.
Scope and verification warning: This guide applies specifically to the MDD datasheet attached to this Flux part, version V 1.0, not to every manufacturer's 2N7002. The project descript...
Created the cited 2N7002 Application and Usage Guide in the project files, covering all seven requested sections. It flags conflicting catalog and datasheet ratings, qualifies replacement compatibility, and identifies sourcing details that could not be verified; confirm the datasheet for the actual supplier stock before production use.
