R4001F from YFW, in a SMA. 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 rectifier diode; the datasheet's pinning section lists pin 1 as Cathode for the R4000F thru R4001F SMA package. |
| 2 | Anode | passive | Anode terminal of the rectifier diode; the datasheet's pinning section lists pin 2 as Anode for the R4000F thru R4001F SMA package. |
