## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K | passive | Cathode (negative terminal, marked with the minus sign in the schematic); the datasheet gives a maximum continuous forward current IF of 25 mA, and a series resistor is required. |
| 2 | A | passive | Anode (positive terminal, marked with the plus sign in the schematic); the datasheet gives a forward voltage VF of 1.75 to 2.35 V at IF=20 mA and a reverse voltage VR maximum of 5 V. |
