KRB551V-40-7-F from KUU, in a SOD-323. 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 datasheet gives a maximum DC blocking voltage of 40 V and a maximum forward current of 350 mA. |
| 2 | A | passive | Anode; the datasheet gives a forward voltage of 0.370 V at IF = 20 mA and 0.600 V at IF = 200 mA. |
