UMW SS26B

UMW · Schottky Diodes · SMB

UMW SS26B from UMW, in a SMB. 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 end of the Schottky diode, marked by the color band on the SMB package; the pinning diagram labels it Pin1.
2 A passive Anode of the Schottky diode (Pin2 in the SMB pinning diagram), opposite the cathode band end.

CAD (KiCad official)

  • Symbol: UMW SS26B
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB (KiCad packages3D, STEP)
  • 3D model files: umw-ss26b-etched.step / umw-ss26b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); umw-ss26b.step / umw-ss26b.glb are the bare package body.
