LTST-C171KRKT from Lite On, in a 0805. 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 (negative) terminal, marked CATHODE on the package drawing; the drawing shows it as the minus polarity terminal. |
| 2 | A | passive | Anode (positive) terminal of the AlInGaP red LED; DC forward current is 30 mA max, with VF of 2.0 V min and 2.4 V max at IF = 20 mA. |
