**RUILON Shenzhen Ruilongyuan Elec** · ESD And Surge Protection (TVS/ESD) · SOT-23

RLST23A032V 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/O1 | passive | Protected line 1, connected to the cathode of the first unidirectional TVS diode (3.3V VRWM, 4.0V min VBR at 1mA, 350W 8/20μs peak pulse power, ±15kV air / ±8kV contact ESD). |
| 2 | I/O2 | passive | Protected line 2, connected to the cathode of the second unidirectional TVS diode (3.3V VRWM, 4.0V min VBR at 1mA, 350W 8/20μs peak pulse power, ±15kV air / ±8kV contact ESD). |
| 3 | GND | power_in | Common anode of both TVS diodes, connected to ground as the return path for surge and ESD current. |
