## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K | passive | Cathode (−) terminal, marked CATHODE on the package drawing, which is the terminal at the notched end of the device. |
| 2 | A | passive | Anode (+) terminal of the InGaN white LED, with an anti-parallel zener diode across the LED; DC forward current is rated 10 mA maximum, and the reverse voltage of 5 V is for the IR test only, not for reverse operation. |
