S1BL from Changjing, 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, marked by the color band on the package; connect to the negative side of the rectifier (1A average forward current, up to 100V repetitive peak reverse voltage for S1BL). |
| 2 | A | passive | Anode terminal of the rectifier diode, opposite the cathode band end of the SOD-123FL package. |
