B5817W-SJ from JUXING, in a SOD-123. 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; the datasheet specifies reverse voltage of 20 V for B5817W (VRRM 20 V, VR 20 V at IR 1 mA). |
| 2 | A | passive | Anode, the end opposite the color band; average forward rectified current 1.0 A, forward voltage 0.450 V max at IF = 1.0 A for B5817W. |
