IR17-21C from Everlight Elec, 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 (-) of the infrared emitting diode, identified by the cathode mark on the package; reverse voltage is limited to 5 V. |
| 2 | A | passive | Anode (+) of the infrared emitting diode; continuous forward current is limited to 65 mA and a series resistor is required for protection. |
