SF14D from FUXINSEMI, 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 | CATHODE | passive | Cathode of the 1.0 A, 200 V super fast rectifier; the color band on the package denotes the cathode end. |
| 2 | ANODE | passive | Anode of the rectifier, which carries the forward rectified current (IO = 1.0 A) from anode to cathode. |
