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. |
