Part Information Review

I reviewed the current part project against the existing datasheet URL and the part-project verification workflow, which recommends treating the datasheet as the source of truth and checking exact project properties and pin metadata before making updates
Datasheet status
  • Datasheet URL already exists, so no web update was needed.
  • Current URL: PDF
  • Note: this is a DigiKey-hosted mirror, not a clearly official manufacturer-hosted URL. A quick web check did not find a clean current onsemi/Motorola product-page PDF, so I left the existing URL unchanged.

Symbol findings
  • Pin count is correct: 3 pins.
  • Pin numbering is correct.
  • Terminal naming is correct.
  • All three terminal components currently have Pin Type = Unspecified.
  • No explicit per-pin descriptions are present beyond the names.
Footprint cross-check

ItemCurrent projectDatasheetResult
Footprint / package intent2N5306.kicad_mod, 3D model TO-92_ONS.stepTO-92Likely match
Pad count33Match
Pad namesEMITTER / COLLECTOR / BASEEmitter / Collector / BaseMatch by function
Footprint findings
  • Package family appears consistent with the datasheet: TO-92.
  • Pad names align with terminal names and datasheet function names.
  • I did not see explicit numeric pad numbers exposed in the layout metadata, so I could not independently verify pad 1/2/3 numbering inside the footprint metadata itself.
  • So: footprint looks consistent, but numeric pad-number exposure is incomplete in the returned layout data.

SeverityIssueNotes
HighDesignator Prefix = UFor a transistor part, this should typically be Q
MediumManufacturer Name missingDatasheet identifies Fairchild Semiconductor
MediumPackage or Case Code missingDatasheet package is TO-92
MediumDescription too short2N5306 is not descriptive enough
LowPin descriptions missingFunctional names exist, but no explicit descriptions
LowPin types all UnspecifiedIncomplete metadata, though not a pinout mismatch
LowPossible empty/unnamed propertyShould be inspected and cleaned up if real
Bottom line
  • Pinout: matches the datasheet.
  • Symbol: functionally correct.
  • Footprint: appears consistent with TO-92 and the named terminals.
  • Main metadata gaps: designator prefix, manufacturer name, package field, richer description, and pin metadata completeness.
If you want, I can fix the flagged metadata next:
  • set Designator Prefix to Q
  • add Manufacturer Name = Fairchild Semiconductor
  • add Package or Case Code = TO-92
  • improve the description
  • add pin descriptions / pin types for EMITTER, COLLECTOR, and BASE
Fix flagged metadata
Use official datasheet
Verify footprint numbering
