## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1 | passive | Terminal 1 of the 0603 LED, the one next to the polarity mark on the package drawing; the datasheet gives no per-pin limit, only device ratings of 30 mA forward current, 60 mA peak pulse current (1/10 duty, 0.1 ms) and 96 mW power dissipation at Ta=25°C. |
| 2 | 2 | passive | Terminal 2 of the 0603 LED, the other terminal of the pair shown in the package drawing; the datasheet gives no per-pin limit, and the anode/cathode assignment is not stated in the text. |
