## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K | passive | Cathode (negative terminal, marked ① and "−" in the outline drawing); the shorter lead, with 2.54mm lead spacing, and reverse current IR ≤10 μA at VR=5V. |
| 2 | A | passive | Anode (positive terminal, marked ② and "+" in the outline drawing); the longer lead (18.0mm vs 16.0mm), with max continuous forward current 20 mA and typical VF 3.0 V at IF=20mA. |
