CAD (KiCad official)

  • Symbol: P4SMA82CA
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA(DO-214AC) (KiCad packages3D, STEP)
  • 3D model files: p4sma82ca-etched.step / p4sma82ca-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); p4sma82ca.step / p4sma82ca.glb are the bare package body.
