S-SMBJ58A from LRC, in a SMB. 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, the terminal marked by the color band on the SMB body (polarity per the Mechanical Data section). |
| 2 | A | passive | Anode, the unmarked terminal opposite the color band on the SMB body. |
