Part Data Review and Verification
Worked for 2 mins 44 sec
Completed the part review and created Part Verification Report. The existing Datasheet URL was already set, pinout and SO-8 footprint matched the Vishay datasheet, and the only cleanup items found were unspecified terminal pin types/descriptions plus a minor MPN separator difference (
_ vs -).Suggested next steps:
- Set explicit Source/Gate/Drain pin descriptions and pin types.
- Normalize the MPN to the manufacturer ordering format if desired.
- Add key electrical specs as searchable part properties.
Set explicit Source, Gate, and Drain pin descriptions and electrical pin types.
Thought for 9 sec
I’ll update the eight terminal properties so each pin has an explicit Source/Gate/Drain description and an appropriate MOSFET electrical pin type, then verify the schematic properties.
Worked for 29 sec
Updated and verified all eight terminal properties.
- Pins 1–3: Source terminal, Pin Type Passive
- Pin 4: Gate control input, Pin Type Input
- Pins 5–8: Drain terminal, Pin Type Passive
No open items.

Footprint/package cross-check
The footprint has eight SMD pads and SO-8 style silk/fab geometry with pin-1 indicator. The visible body/silk dimensions are consistent with narrow SOIC-8 style geometry, and the datasheet package is SO-8 / SOIC narrow, JEDEC MS-012. No footprint pad numbering mismatch was found from the available layout data.
Mismatches / cleanup items
- No critical pinout mismatch found.
- No critical footprint/package mismatch found.
- Datasheet URL was already set; no update was needed.
- Symbol terminal descriptions are implicit in the terminal designators (S_1, S_2, S_3, G, D_1, D_2, D_3, D_4), but each terminal's Pin Type property is still set to
Unspecified. For better library quality, set Source/Drain/Gate pin descriptions and electrical pin types explicitly. - MPN formatting differs slightly: project uses
SQ4435EY-T1_GE3, while datasheet ordering line showsSQ4435EY-T1-GE3. This appears to be separator formatting rather than a functional mismatch, but distributor/manufacturer ordering should be checked if exact orderability matters.
