UMW SS16A

UMW · Schottky Diodes · SMA(DO-214AC)

UMW SS16A 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, the end marked by the color band; the datasheet shows Pin1 and Pin2 on the SMA drawing and states the color band denotes the cathode end.
2 A passive Anode, the end opposite the color band; the datasheet labels it Pin2 on the SMA drawing, with 60V maximum repetitive peak reverse voltage and 1A average forward current for SS16A.

CAD (KiCad official)

  • Symbol: UMW SS16A
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA(DO-214AC) (KiCad packages3D, STEP)
  • 3D model files: umw-ss16a-etched.step / umw-ss16a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); umw-ss16a.step / umw-ss16a.glb are the bare package body.
