**RUILON(Shenzhen Ruilongyuan Elec)** · ESD Protection Devices · SOD-923

RLSD92A031V from RUILON(Shenzhen Ruilongyuan Elec), in a SOD-923. 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 | CATHODE | passive | Cathode terminal of the unidirectional TVS/ESD diode, which protects one line at a working peak reverse voltage (VRWM) of 3.3V. |
| 2 | ANODE | passive | Anode terminal of the unidirectional TVS/ESD diode, paired with pin 1 CATHODE for the single protected line. |
