## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K | passive | Cathode of the green AlGaInP LED, at the polarity-mark end of the package; reverse voltage is limited to 5V maximum (IR 10uA max at VR=5V). |
| 2 | A | passive | Anode of the green AlGaInP LED; forward current is 20mA typical test condition (30mA DC max, 150mA peak at 1/10 duty, 0.1ms pulse), with VF 2.1V typ and 2.5V max at 20mA. |
