SK104B from MDD（Microdiode Electronics）, 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, the end marked with the color band; SK104B has 40 V maximum repetitive peak reverse voltage and 10.0 A average forward rectified current. |
| 2 | A | passive | Anode terminal of the Schottky rectifier; maximum instantaneous forward voltage is 0.65 V at 10.0 A for the SK102B-SK1045B group. |
