SMFJ54CA 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 | A1 | passive | Bidirectional TVS terminal 1 (no polarity, interchangeable with the other terminal); the SMFJ54CA has VR = 54 V stand-off, VBR 60 V min to 66.3 V max at 1 mA, and VC of 87.1 V at Ipp = 2.3 A. |
| 2 | A2 | passive | Bidirectional TVS terminal 2 (no polarity, interchangeable with the other terminal); peak pulse power is rated 200 W (10/1000us) and the clamp is symmetric in both directions. |
