DS12W-MS from MSKSEMI, in a SOD-123FL. 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; DS12W-MS has 20V max DC blocking voltage and 1.0A average forward rectified current. |
| 2 | A | passive | Anode terminal of the Schottky rectifier; forward voltage is 0.55V max at 1.0A for DS12W-MS through DS14W-MS. |
