S-SMDJ58A from LRC, in a SMC. 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 | K | passive | Cathode terminal, marked by the color band on the SMC (DO-214AB) body; connect to the protected line (positive side) of this unidirectional TVS. |
| 2 | A | passive | Anode terminal, the end without the color band on the SMC (DO-214AB) body; connect to ground/return of this unidirectional TVS. |
