SMFJ58A from BORN, in a SOD-123F. 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 of the unidirectional TVS (marked end with the band), connected to the protected line; reverse stand-off voltage VR is 58 V and breakdown voltage is 64.4 V min to 71.2 V max at 1 mA. |
| 2 | A | passive | Anode of the unidirectional TVS, normally connected to ground; maximum clamping voltage is 93.6 V at 2.1 A peak pulse current. |
