# B5817WL

**Shikues** · Schottky Diodes · SOD-123F

B5817WL from Shikues, in a SOD-123F. 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 | Cathode | passive | Cathode terminal of the B5817WL Schottky barrier rectifier; the datasheet pinning table gives only the name 'Cathode' with no further electrical limits for this pin. |
| 2 | Anode | passive | Anode terminal of the B5817WL Schottky barrier rectifier; the datasheet pinning table gives only the name 'Anode' with no further electrical limits for this pin. |
