XBL354B-TAG from XBLW, in a SOP-4-2.54mm. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Anode/Cathode | input | Input LED terminal 1; the input is two anti-parallel infrared emitting diodes (AC input response), so this pin is anode of one diode and cathode of the other. |
| 2 | Cathode/Anode | input | Input LED terminal 2; the input is two anti-parallel infrared emitting diodes (AC input response), so this pin is cathode of one diode and anode of the other. |
| 3 | Emitter | passive | Phototransistor emitter output pin. |
| 4 | Collector | passive | Phototransistor collector output pin, with minimum BVCEO of 70 V guaranteed. |
