SET23A03L02 from Brightking, in a SOT-23. 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 | LINE 1 | passive | I/O line 1 protected against ESD; 3.3V reverse stand-off voltage (VRWM), 4V min breakdown at 1mA, 5uA max leakage at VR=3.3V. |
| 2 | LINE 2 | passive | I/O line 2 protected against ESD; 3.3V reverse stand-off voltage (VRWM), 4V min breakdown at 1mA, 5uA max leakage at VR=3.3V. |
| 3 | GND | power_in | Common ground reference for the unidirectional protection diodes (pin 3 on the package drawing); in the bidirectional configuration it is left as the unconnected X pin. |
