Part Datasheet Review and Validation
Thought for 4 sec
I’ll review the part metadata, find and set the official datasheet if missing, then verify symbol/footprint/pin details against it and summarize any mismatches.
Worked for 2 mins
The existing datasheet URL is present but resolves to a Skyworks 404, so I’m updating it to the current official Skyworks PDF URL found during review.
Worked for 2 mins 36 sec
Reviewed SMS7630-005LF and updated the stale Skyworks datasheet URL to the current official PDF. I created the detailed audit here: SMS7630-005LF Part Review.
Open items:
- Symbol pins exist as 1/2/3, but pin descriptions are missing.
- Pin Type is still
Unspecifiedfor all terminals. - Component review flags missing Pin Group, Pin Orientation, and Section metadata.
- Footprint is a standard SOT-23-3 footprint and broadly matches the package, but Skyworks does not provide a recommended land pattern in the extracted datasheet text.
Suggested next steps:
- Populate terminal descriptions from the datasheet.
- Set pin type/group/orientation/section metadata to clear part review warnings.
- Optionally validate the SOT-23 land pattern against your assembly vendor’s preferred rules.

Table
| Pin | Function |
|---|---|
| 1 | Anode of diode 1 |
| 2 | Cathode of diode 2 |
| 3 | Common series junction: cathode of diode 1 / anode of diode 2 |
Schematic symbol cross-check
Current symbol consists of three terminal components with pin numbers 1, 2, and 3. Symbol pin positions place pins 1 and 2 on the left and pin 3 on the right, which is compatible with a 3-terminal series-pair diode symbol.
Mismatches / gaps:
- Terminal pin descriptions are not populated. They should be pin 1 = anode of diode 1, pin 2 = cathode of diode 2, pin 3 = cathode of diode 1 / anode of diode 2 common series junction.
- Pin Type is currently Unspecified for all three terminals.
- Component review reports missing parametric symbol properties for pins 1, 2, and 3: Pin Group, Pin Orientation, and Section.
Footprint cross-check
Current footprint asset: SOT95P237X112-3N.kicad_mod, described as SOT-23.
Footprint pad geometry from the asset:
- Pad 1: SMD rectangle at (-1.00 mm, -0.95 mm), size 0.60 mm x 1.35 mm, rotated 90°
- Pad 2: SMD rectangle at (-1.00 mm, +0.95 mm), size 0.60 mm x 1.35 mm, rotated 90°
- Pad 3: SMD rectangle at (+1.00 mm, 0.00 mm), size 0.60 mm x 1.35 mm, rotated 90°
- Courtyard: approximately 3.85 mm x 3.54 mm
- Fab body outline: approximately 1.30 mm x 2.92 mm, with a pin-1 chamfer/marker
Datasheet SOT-23 package dimensions include:
- Body length: 2.80 to 3.04 mm
- Body width: 1.20 to 1.40 mm / 2.10 to 2.64 mm depending on dimension axis in drawing
- Height: 0.89 to 1.12 mm
- Lead pitch: 0.95 mm reference
- e1 span: 1.92 mm reference
Assessment:
- The footprint is a standard 3-pad SOT-23 footprint and is broadly consistent with the datasheet package/pin count.
- The pad numbering pattern is mirrored/rotated relative to the datasheet's printed top-view drawing, but that can still be valid depending on footprint orientation. The key requirement is that symbol pin 1 maps to footprint pad 1, pin 2 to pad 2, and pin 3 to pad 3; those pad numbers exist.
- The Skyworks datasheet provides package dimensions but no manufacturer-specific recommended PCB land pattern in the extracted text, so the footprint cannot be validated against a Skyworks land pattern, only against generic SOT-23 conventions and package dimensions.
Recommended fixes
- Populate terminal descriptions:
- Pin 1: Anode of diode 1
- Pin 2: Cathode of diode 2
- Pin 3: Cathode of diode 1 / anode of diode 2, common series junction
- Set symbol parametric metadata to clear review warnings:
- Pin Group / Section: Diode Pair or Terminals
- Pin Orientation: match the existing symbol placement, with pins 1 and 2 left-facing and pin 3 right-facing if supported by the property model
- Optionally set Pin Type more specifically if Flux supports diode terminal types; otherwise Passive is preferable to Unspecified for ERC behavior.
- If high-confidence manufacturing validation is required, compare the SOT95P237X112-3N land pattern against the assembly vendor's preferred SOT-23 land pattern or IPC nominal rules.
