RLST23A122V from RUILON Shenzhen Ruilongyuan Elec, 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 | I/O 1 | passive | Protected line 1 (TVS cathode to pin 3), 12V reverse stand-off, 13.3V min breakdown at 1mA, 19V clamp at 1A (8/20µs). |
| 2 | I/O 2 | passive | Protected line 2 (TVS cathode to pin 3), 12V reverse stand-off, 13.3V min breakdown at 1mA, 19V clamp at 1A (8/20µs). |
| 3 | GND | power_in | Common anode of both TVS diodes, connected to ground/reference for the two protected lines. |
