FR154 from LangJie, in a DO-15. 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 by the color band; the diode blocks up to 400 V (VRRM/VDC for FR154) in reverse and conducts 1.5 A average forward current. |
| 2 | A | passive | Anode, the end opposite the color band; forward voltage is at most 1.3 V at 1.5 A. |
