FR104W F4 from MSKSEMI, 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; the datasheet states 'Polarity: Color band denotes cathode end'. |
| 2 | A | passive | Anode; the end opposite the cathode color band, with a 1.0 A average forward current (IF(AV)) rating at Ta = 65 °C. |
