LTW-C191DS5 from Lite On, in a 0603. 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 terminal, marked with the cathode dot on the package drawing; the rated reverse voltage is 5 V and DC forward current is 20 mA max. |
| 2 | A | passive | Anode terminal (+), the opposite soldering terminal from the cathode mark; forward voltage is 2.70 to 3.15 V at IF = 5 mA. |
