Completed the PLT5 450B review and created the detailed report: PLT5 450B Part Review.
Open items:
- Pin numbers/functions match the datasheet.
- Main issues flagged: description says 80 mW vs datasheet 100 mW typ, Datasheet URL is a stored copy rather than the current official ams OSRAM URL, pin descriptions are not populated, package metadata is missing/implicit, and the Flux footprint appears to have a scaling/rendering issue.
- I filed an internal part-quality report for the footprint scaling concern.
Suggested next steps:
- Update metadata: description, package, lifecycle/status, and official datasheet URL.
- Add explicit Pin Description properties for pins 1–3.
- Fix or override the footprint pad geometry before using this part in a PCB.

PLT5 450B Part Review
Review date: 2026-07-14
Scope
Reviewed the published part project for OSRAM / ams OSRAM PLT5 450B against the available part metadata, schematic terminals, PCB footprint, 3D/model assets, and the datasheet information available in the project and on the official ams OSRAM product page.

The part already had a Datasheet URL property set, so I did not change it. I also found the current official ams OSRAM product page and official PDF:
- Official product page: https://ams-osram.com/products/lasers/color-lasers-eel/osram-metal-can-to56-plt5-450b
- Official current datasheet PDF: https://look.ams-osram.com/m/711b74151583f43/original/PLT5-450B.pdf
Datasheet source notes
The Datasheet URL currently stored in the project points to a Flux storage copy. The official ams OSRAM page currently serves a newer official PDF identified by web search as preliminary datasheet version 0.6 dated 2023-03-01 and marks the product discontinued. The stored project PDF appears to contain the same core electrical and pinout data, but may be an older copy/version.

Datasheet pinout
Table
| Pin | Datasheet description |
|---|---|
| 1 | LD Anode |
| 2 | Case |
| 3 | LD Cathode |
Schematic symbol cross-check
Table
| Schematic terminal | Flux Pin Number property | Datasheet function | Result |
|---|---|---|---|
| LD_A | 1 | LD Anode | Match |
| CASE | 2 | Case | Match |
| LD_K | 3 | LD Cathode | Match |
Symbol-level observations:
- The terminal naming and pin numbers match the datasheet pinout.
- The terminal Pin Type values are all Unspecified. For a cleaner symbol, LD_A could be typed as Passive or Power In/Anode-equivalent, LD_K as Passive, and CASE as Passive/Mechanical/Shield depending Flux conventions, but this is not a datasheet mismatch.
- No explicit Pin Description properties were found on the terminal components; the designators themselves encode the functions. Adding Pin Description = LD Anode / Case / LD Cathode would make the symbol more self-documenting.
Footprint cross-check
The KiCad footprint asset embedded in the part contains plausible TO56 geometry:
- Footprint name: PLT5450B
- Description: PLT5 450B-2
- Intended pads in asset:
- Pad 1: through-hole circular, at (1.000 mm, 0), size 1.000 mm, drill 0.65 mm
- Pad 2: through-hole circular, at (0, -1.000 mm), size 1.000 mm, drill 0.65 mm
- Pad 3: through-hole circular, at (-1.000 mm, 0), size 1.000 mm, drill 0.65 mm
- Body/courtyard/silkscreen geometry approximates the TO56 package, including a 5.6 mm class circular body and orientation feature.
Datasheet mechanical support:
- Package: TO56 metal can
- Lead diameter: 0.45 mm ±0.05 mm
- Datasheet mechanical drawing indicates 1 mm / 2 mm class lead spacing dimensions and 5.6 mm can outline.
- No explicit recommended PCB footprint or drill size is provided in the datasheet.
Footprint result:
- The pad numbering and intended pad geometry in the imported KiCad asset appear directionally consistent with the datasheet TO56 pinout and lead dimensions.
- A 0.65 mm drill for 0.45 mm ±0.05 mm leads is plausible.
- The datasheet does not provide a recommended land pattern, so exact annular-ring/pad-size validation cannot be made from the datasheet alone.
Mismatches and issues flagged
-
Description power mismatch: the project description says 80 mW, while the official PLT5 450B datasheet lists 100 mW typical continuous-wave optical output power at TC = 25 °C and 120 mW max peak optical output rating. The 80 mW value may refer to a related older PL 450B listing, not this PLT5 450B datasheet.
-
Datasheet URL freshness: the part has a Datasheet URL set, but it points to a stored PDF copy rather than the current official ams OSRAM URL. The official page now marks PLT5 450B discontinued and serves the official PDF at https://look.ams-osram.com/m/711b74151583f43/original/PLT5-450B.pdf.
-
Part Type is broad/nonstandard: Flux metadata says Part Type = Diodes. A more specific type such as Laser Diode / LED / Diode, depending Flux taxonomy, would better match the device.
-
Missing explicit Package property: the project metadata does not show an explicit Package or Package or Case Code property, although the footprint and datasheet clearly indicate TO56.
-
Pin descriptions are implicit only: schematic terminal designators and pin numbers match, but terminal Pin Description fields are not populated.
-
Footprint scaling/rendering concern: the layout tree shows the embedded KiCad footprint asset with plausible mm-scale pad data, but the computed Flux pad nodes and rendered shapes appear at approximately 0.001 mm scale, and the footprint image renders effectively invisible. This looks like an import/scaling issue in the Flux footprint representation. I filed an internal part-quality report for review.
Recommended cleanup actions
- Update Description to state 450 nm, 100 mW typ optical output, TO56 blue laser diode.
- Optionally replace the Datasheet URL with the official ams OSRAM PDF URL.
- Add Package / Package or Case Code = TO56 if the project property schema allows it.
- Add terminal Pin Description properties for all three pins.
- Fix or override the Flux pad geometry if this part will be used on a PCB: pad centers should match the intended TO56 geometry, with pad/drill sizes suitable for 0.45 mm ±0.05 mm leads.
- Consider marking lifecycle/status as discontinued if lifecycle metadata is available.
