CAD (KiCad official)

  • Symbol: 2SA1294
  • Footprint: Package_TO_SOT_THT:TO-3P-3_Vertical
  • 3D model: TO-3PN (KiCad packages3D, STEP)
  • 3D model files: 2sa1294-etched.step / 2sa1294-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 2sa1294.step / 2sa1294.glb are the bare package body.

Provenance

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

  • Datasheet: SPTECH datasheet (2 pp, sha256 0646231e13c80dec, retrieved 2026-11-07, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text+vision), consensus claude-opus-5-5 (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).
