US2GA

onsemi · Fast Recovery / High Efficiency Diodes · SMA(DO-214AC)

US2GA from onsemi, in a SMA(DO-214AC). 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 Cathode passive Cathode terminal, marked by the color band on the SMA package; the band denotes the cathode.
2 Anode passive Anode terminal of the rectifier, opposite the cathode (color band) end.

CAD (KiCad official)

  • Symbol: US2GA
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA(DO-214AC) (KiCad packages3D, STEP)
  • 3D model files: us2ga-etched.step / us2ga-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); us2ga.step / us2ga.glb are the bare package body.
