UMW SS110A

UMW · Schottky Diodes · SMA(DO-214AC)

UMW SS110A from UMW, 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 K passive Cathode terminal of the Schottky rectifier, marked by the color band on the SMA molded body; the part is rated 100V VRRM and 1A average forward current.
2 A passive Anode terminal of the Schottky rectifier, opposite the color-banded end of the SMA body; the part has a maximum forward voltage of 0.85V at 1.0A.

CAD (KiCad official)

  • Symbol: UMW SS110A
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA(DO-214AC) (KiCad packages3D, STEP)
  • 3D model files: umw-ss110a-etched.step / umw-ss110a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); umw-ss110a.step / umw-ss110a.glb are the bare package body.
