CAD (KiCad official)

  • Symbol: P4SMA440A
  • Footprint: Diode_SMD:D_SMA
  • 3D model: DO-214AC (KiCad packages3D, STEP)
  • 3D model files: p4sma440a-etched.step / p4sma440a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); p4sma440a.step / p4sma440a.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Littelfuse datasheet (6 pp, sha256 852b4d7b8018f3b1, retrieved 2026-10-13, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins, primary cathode-band convention (convention), consensus off (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
