**NEWOPTO** · Ambient Light Sensors · 0805

XYC-PT0805AC-LB1-S from NEWOPTO, in a 0805. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | E | passive | Emitter of the NPN phototransistor. Marked '-' / Emitter on the package outline; connect to the low side (typically through a load resistor Rss ~1 kOhm to GND for the standard Vout tap shown in the application circuit). |
| 2 | C | passive | Collector of the NPN phototransistor. Marked '+' / Collector on the package outline; typically tied to VCE = 5 V supply per the application circuit. Absolute maximum VCEO = 30 V. |
