Audit complete. The Datasheet URL was already populated, so no property update was needed; I verified the official ams OSRAM datasheet.
Key issues:
  • Critical: Pin numbering appears reversed—current Pin 1 = K and Pin 2 = A; expected Pin 1 = A, Pin 2 = K.
  • Footprint pitch is correct at 5.08 mm, but the body/silkscreen dimensions do not match the official 5.15 × 3.85 × 2.05 mm package.
  • Pin types/descriptions are incomplete.
  • The part is officially discontinued.

Correct the pin numbering, terminal descriptions, and footprint body/silkscreen geometry to match the official datasheet.

I’ll correct the terminal numbering and metadata first, then rebuild the footprint body and silkscreen to the official 5.15 × 3.85 mm package dimensions and verify the result.

Pin 1 is now the anode and Pin 2 the cathode, with passive types and datasheet-based descriptions. I’m replacing the old package outline with a 5.15 × 3.85 mm body and moving the polarity marking to the cathode side.

Corrections completed and verified:
  • Pin 1 = A, “Photodiode anode,” passive.
  • Pin 2 = K, “Photodiode cathode; package-marked lead,” passive.
  • Pad mapping is now correct at 5.08 mm pitch.
  • Body and silkscreen are corrected to 5.15 × 3.85 mm, with pad-clearance gaps and a pin-2 cathode mark.
The corrected status is recorded in the Part Audit Report. The imported footprint’s legacy filename remains unchanged, but its effective geometry is overridden correctly.
