RLSD32A031LC from RUILON Shenzhen Ruilongyuan Elec, in a SOD-323. 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 | 1 | passive | Bidirectional protected line (power or I/O port) connected to the TVS array, with 300 W peak pulse power (8/20µs) and ±8 kV contact / ±15 kV air ESD rating. |
| 2 | 2 | passive | Second terminal of the bidirectional TVS, normally tied to ground or the return of the protected line, with operating range -55 to 150 °C. |
