UMW SS14A

UMW · Schottky Diodes · SMA(DO-214AC)

UMW SS14A 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 Pin 1 of the SMA molded body, which the datasheet marks by the color band denoting the cathode end; the SS14A is rated 40 V VRRM and 1 A average forward rectified current.
2 A passive Pin 2 of the SMA molded body, the opposite terminal to the color-banded cathode end; the SS14A is rated 40 V VRRM and 1 A average forward rectified current.

CAD (KiCad official)

  • Symbol: UMW SS14A
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA(DO-214AC) (KiCad packages3D, STEP)
  • 3D model files: umw-ss14a-etched.step / umw-ss14a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); umw-ss14a.step / umw-ss14a.glb are the bare package body.
