Part Review Audit

flux

I’ll inspect the current part metadata, find and set the official datasheet if missing, then compare symbol/footprint/pins against the datasheet and report any mismatches.

Completed the IRLB4030PBF part review and saved the detailed findings in IRLB4030PBF Part Review. The Datasheet URL was already set to an official Infineon PDF, so I did not change it.
Open items:
  • Package or Case Code is too generic (TO); should be TO-220AB or PG-TO220-3-904.
  • Terminal Pin Type and Pin Description fields are incomplete/unspecified.
  • No critical footprint mismatch found; 3-pin TO-220AB pad order and pitch match the datasheet.
Suggested next steps:
  1. Update package metadata to TO-220AB.
  2. Add Gate/Drain/Source pin descriptions.
  3. Set appropriate pin types for ERC behavior.

Note: one scrape of the newer PDF incorrectly extracted VDS as 30 V. The official product page, alternate official PDF scrape, distributors, and the project description all agree this part is 100 V, so 100 V is the correct value.
Cross-check results
Symbol / schematic pins
  • Pin numbering matches the datasheet:
    • Pin 1 = Gate
    • Pin 2 = Drain
    • Pin 3 = Source
  • Symbol placement corresponds to a conventional N-channel MOSFET layout: Gate on the left, Drain above/right, Source below/right.
  • Mismatch/incomplete metadata: terminal Pin Type values are all Unspecified; these should ideally be Gate = Input, Drain = Passive/Power, Source = Passive/Power depending Flux convention.
  • Mismatch/incomplete metadata: Pin Description properties are not populated on the terminals. They should ideally read Gate, Drain, and Source.
Footprint
  • Pad count matches: 3 through-hole pads.
  • Pad numbering and order match the TO-220AB datasheet: 1-2-3 left-to-right at 2.54 mm pitch.
  • Pad geometry appears plausible for TO-220AB leads: 2.07 mm pads with 1.38 mm drills. The datasheet lead widths are roughly 0.69-1.01 mm and lead thickness 0.36-0.61 mm, so a 1.38 mm drill is mechanically reasonable.
  • Pin 2 drain pad is present, and the datasheet tab is also Drain. The footprint does not model a separate electrical tab pad, which is typical for a vertical TO-220 lead footprint unless a board-mounted tab/heatsink feature is required.
  • No critical footprint mismatch found from the available information.
Part properties
  • Datasheet URL was already set to an official Infineon PDF, so no update was required.
  • Package or Case Code is currently TO, which is too generic. Datasheet and product page identify the package as TO-220AB / PG-TO220-3-904.
  • Description in project context says 100 V, 180 A, 3-pin TO-220AB Infineon, which matches the official product page/datasheet.
Flagged mismatches / recommended cleanup
  1. Update Package or Case Code from TO to TO-220AB or PG-TO220-3-904 for precision.
  2. Add terminal pin descriptions:
    • Pin 1: Gate
    • Pin 2: Drain
    • Pin 3: Source
  3. Set terminal pin types instead of leaving them Unspecified:
    • Gate: Input
    • Drain/Source: Passive or Power/Passive according to the desired ERC behavior.
  4. Optional: keep the current official datasheet URL, or replace it with the newer canonical Infineon asset URL if you prefer stable human-readable paths.
