I reviewed the current part project and compared it against the official ST listing/datasheet URL already present in the project.
Summary
The project already has the official datasheet URL set to ST’s PDF, so there’s no missing Datasheet property to fill in. For part-project audits like this, the key checks are that the datasheet URL is canonical, project property names match Flux’s exact default labels, and the terminal count matches the datasheet exactly, including any exposed pads
What looks correct

Project metadata


FieldCurrent valueAssessment
Manufacturer Part NumberSTL11N3LLH6Looks correct
Manufacturer NameSTMicroelectronicsLooks correct
Part TypeTransistorsBroadly correct, though MOSFET would be more specific if you want tighter classification
Designator PrefixQCorrect for a transistor
Datasheet URLOfficial ST PDFCorrect / no update needed
Description“N-channel 30 V, 6 m typ., 11 A STripFET H6 Power MOSFET in a PowerFLAT 3.3x3.3 package”Consistent with ST headline specs
Key specs from the official ST source
  • Type: N-channel STripFET H6 power MOSFET
  • VDS: 30 V
  • RDS(on): 6 mΩ typ.
  • ID: 11 A
  • Package: PowerFLAT 3.3 x 3.3

Symbol findings
  • The symbol currently exposes 5 terminals: three source pins, one gate, one drain.
  • All five terminals have Pin Type = Unspecified.
  • I do not see pin descriptions populated for these terminals.
  • For part verification, Flux guidance is to match the datasheet exactly and not leave pin metadata vague when the datasheet defines it
Footprint audit Layout findings
The footprint contains:
  • Pads for S_1, S_2, S_3, G, and D
  • Plus three additional footprint pads labeled 6, 7, and 8
Likely mismatch
  • The schematic symbol models 5 terminals, but the footprint appears to implement 8 copper pads.
  • That is a possible pin-count mismatch.
  • Flux’s part-sync guidance is explicit that the terminal count must match the datasheet exactly, including exposed/thermal pads
Because the datasheet text extraction available here did not expose the package figure’s pin legend cleanly, I can’t state with full confidence whether pads 6/7/8 are electrically duplicated source/drain lands or a separate exposed-pad convention. But as it stands, the project should be treated as needs verification.

Flagged issues


IssueSeverityNotes
All terminal pin types are UnspecifiedMediumReduces symbol quality/ERC usefulness
Terminal pin descriptions are missingMediumShould be short functional labels
Symbol shows 5 terminals while footprint shows 8 padsHighPossible datasheet/footprint mismatch
Part Type is generic (Transistors)LowMore specific MOSFET may be better
Package code property is not explicitly present as a dedicated propertyLowCould add PowerFLAT 3.3 x 3.3 / canonical case code
Recommended next fixes
  • Set project-level properties more explicitly:
    • Part Type → MOSFET
    • Package or Case Code → PowerFLAT 3.3 x 3.3
  • Set terminal metadata on S_1, S_2, S_3, G, and D
  • Verify whether footprint pads 6/7/8 need matching symbol terminals or whether the footprint should be replaced with one whose electrical pad model matches the symbol
I can apply the project property cleanup next. For the symbol/terminal and footprint-side fixes, I’d want to handle those as follow-up edits after we confirm how ST defines pads 6/7/8 in this package.
