F1 from SY(顺烨), 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 terminal, the end marked with the polarity band on the body; F1 is rated 50V VRRM/VDC, 35V VRMS, 1.0A average forward current. |
| 2 | A | passive | Anode terminal, the end opposite the polarity band; forward voltage max 1.30V at 1.0A, peak surge 35.0A (8.3ms). |
