SET23A24L02 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 | Protected I/O line 1 (two-unidirectional-line use) with 24V reverse stand-off voltage, 26.7V min breakdown at 1mA and 1µA max leakage per I/O pin. |
| 2 | LINE 2 | passive | Protected I/O line 2 (two-unidirectional-line use) with 24V reverse stand-off voltage, 26.7V min breakdown at 1mA and 1µA max leakage per I/O pin. |
| 3 | GND | power_in | Common cathode connection, tied to ground when protecting two unidirectional lines (80pF max capacitance between I/O pins and GND), and shown as X when used as one bidirectional line between pins 1 and 2. |
