## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K | passive | Cathode terminal, marked by the green cathode mark on the package; reverse voltage limited to 5 V (VR) and forward current to 20 mA DC (100 mA peak at 1/10 duty, 0.1 ms). |
| 2 | A | passive | Anode terminal; needs a series current-limiting resistor, with Vf typically 2.8 V (max 3.2 V) at IF=5 mA. |
