## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K | passive | Cathode (marked '-' in the polarity diagram); the anode mark on the bottom view is at the opposite terminal, pin 2; continuous forward current limited to 25 mA per segment and reverse voltage to 10 V. |
| 2 | A | passive | Anode (marked '+' in the polarity diagram, identified by the anode mark on the bottom view); forward voltage 1.75 to 2.35 V at IF = 20 mA, with a series resistor required. |
