## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K | passive | Cathode of the green AlGaInP LED, on the polarity-marked end of the package; the reverse voltage rating is 5 V. |
| 2 | A | passive | Anode of the green AlGaInP LED; forward current is 30 mA DC max (150 mA peak at 1/10 duty, 0.1 ms pulse), with VF typically 2.1 V and 2.5 V max at IF=20 mA. |
