SM320A

LRC · Schottky Barrier Diodes (SBD) · DO-214AC(SMA)

SM320A from LRC, in a DO-214AC(SMA). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 K passive Cathode, the end marked by the color band; the datasheet states 'Polarity: Color band denotes cathode end'.
2 A passive Anode terminal of the Schottky barrier rectifier (the end opposite the cathode color band).

CAD (KiCad official)

  • Symbol: SM320A
  • Footprint: Diode_SMD:D_SMA
  • 3D model: DO-214AC(SMA) (KiCad packages3D, STEP)
  • 3D model files: sm320a-etched.step / sm320a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sm320a.step / sm320a.glb are the bare package body.
