CAD (KiCad official)

  • Symbol: THVD1419DT
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: thvd1419dt-etched.step / thvd1419dt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); thvd1419dt.step / thvd1419dt.glb are the bare package body.

Provenance

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