FR105 from LangJie, in a DO-41. 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, the end marked with the color band; the device blocks up to 600 V (VRRM/VDC for FR105) in reverse and conducts 1.0 A average forward current. |
| 2 | A | passive | Anode, the axial lead opposite the color band; maximum forward voltage is 1.3 V at 1.0 A. |
