1N5925BRLG from onsemi, 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 | CATHODE | passive | Cathode lead, marked by the polarity band on the body; the datasheet states the primary path of conduction is through the cathode lead. |
| 2 | ANODE | passive | Anode lead; the datasheet gives a maximum forward voltage of 1.5 V at IF = 200 mAdc for all types in the series. |
