## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K | passive | Cathode (negative terminal, marked by the cathode mark on the bottom view); continuous forward current 25 mA max, reverse voltage 5 V max. |
| 2 | A | passive | Anode (positive terminal); forward voltage 2.6 V min to 3.1 V max at IF = 5 mA, continuous forward current 25 mA max, so a series resistor is required. |
