CAD (KiCad official)

  • Symbol: AP7381-33V-A
  • Footprint: Package_TO_SOT_THT:TO-92_Inline
  • 3D model: TO-92 (KiCad packages3D, STEP)
  • 3D model files: ap7381-33v-a-etched.step / ap7381-33v-a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ap7381-33v-a.step / ap7381-33v-a.glb are the bare package body.
