Audit complete. Metadata identifies an Excelitas C30737MH-230-80A, 2-terminal silicon APD in a 1.75 × 2.0 mm LLC SMD package; the existing datasheet is valid, so no URL update was required.
Key specs: 230 µm active diameter, 800 nm peak response, 500–1100 nm spectral range, 120–160 V breakdown bin, 1 pF typical capacitance, 1.3 GHz bandwidth, and 0.05 nA typical dark current.
Critical mismatch: the symbol, footprint, and 3D model are still VEMD2704 assets. The Excelitas drawing labels terminals ANODE/CATHODE but does not assign pin numbers, so the current 1=K, 2=A numbering is unverified. I filed an internal part-quality report; this part should not be used for PCB fabrication until its assets are replaced.
